How to Book Cheap Airplane Flights Online

Traveling the world or even just visiting family shouldn’t break the bank. One of the biggest expenses when planning a trip is often the cost of flights. Fortunately, with the right strategies and a little patience, it’s entirely possible to snag cheap airplane tickets online. This comprehensive guide will walk you through everything you need to know to become a savvy flight-booking expert, saving you money on your next adventure.

Understanding the Dynamics of Flight Pricing

Before diving into the specific techniques, it’s crucial to understand why flight prices fluctuate. Airlines use complex algorithms that take into account a multitude of factors, including:

• Demand: Higher demand (e.g., during holidays, school breaks, peak seasons) generally leads to higher prices. Flights to popular destinations and at popular times are almost always more expensive.
• Time of Year: The seasons significantly impact airfare. Summer and winter holidays are prime examples of peak season, while shoulder seasons (spring and fall) often offer better deals.
• Day of the Week: Traditionally, flights departing on Fridays and Sundays are more expensive, as are flights during the middle of the week (Tuesday, Wednesday, Thursday) are often cheaper. However, this isn’t a hard-and-fast rule and can vary depending on the route and other factors.
• Time of Day: Flights that depart early in the morning or late at night are sometimes cheaper, as fewer people prefer those inconvenient times. Red-eye flights (overnight flights) are a common example.
• Fuel Prices: When fuel prices rise, airlines often pass on those costs to consumers in the form of higher ticket prices.
• Competition: Routes with more competition among airlines tend to have lower prices. Airlines constantly adjust their pricing to remain competitive with other carriers on the same routes.
• Booking Time: Booking too early or too late can both lead to higher prices. There’s a “sweet spot” when booking, often a few months in advance for domestic flights and even further in advance for international flights.
• Special Events: Major events like concerts, festivals, and sporting events can drive up flight prices to nearby destinations.
• Airline Sales & Promotions: Airlines frequently offer sales and promotions to fill empty seats. These deals can be a great way to save money, but they’re often time-sensitive.
• Load Factor: The load factor refers to the percentage of seats on a flight that are occupied. If a flight is expected to be full, the prices will likely be higher. If it’s expected to be mostly empty, airlines may lower prices to attract more passengers.

Understanding these factors empowers you to make informed decisions about when and how to book your flights.

The Best Search Engines and Online Travel Agencies (OTAs)

The first step in finding cheap flights is using the right search engines and online travel agencies (OTAs). While no single platform consistently offers the absolute lowest price for every flight, some are generally more reliable and user-friendly than others. Here’s a rundown of some of the top contenders:

• Google Flights: Google Flights is a powerful and versatile tool that allows you to search for flights across multiple airlines and OTAs. Its calendar view is particularly helpful for identifying the cheapest days to fly within a given month. The price tracking feature is excellent for monitoring the price of a specific flight or route and receiving email alerts when the price changes. Explore feature lets you discover destinations within a budget.
• Skyscanner: Skyscanner is another popular search engine that compares flights from a wide range of airlines and OTAs. It’s particularly useful for finding flights to multiple destinations or for being flexible with your destination. Skyscanner’s “Everywhere” search is a great way to find the cheapest places to fly from your origin airport.
• Kayak: Kayak searches hundreds of travel sites to find the best deals on flights, hotels, and rental cars. It also offers a “Hacker Fare” feature, which combines one-way tickets from different airlines to potentially save you money. Kayak’s price alert system can notify you when prices drop for your desired flight.
• Momondo: Momondo is known for its comprehensive search results and its ability to find slightly different deals than other platforms. It often uncovers hidden fares that other search engines miss. Momondo is part of the Kayak group.
• Kiwi.com: Kiwi.com specializes in finding connecting flights that aren’t typically offered by traditional airlines, often resulting in significant savings. However, be aware of the risks associated with self-transfer connections, such as missed connections due to delays.
• Directly with Airlines: Don’t overlook the importance of checking airline websites directly. Sometimes, airlines offer exclusive deals that aren’t available through third-party search engines. Southwest Airlines, for example, doesn’t list its fares on most OTAs.
• Online Travel Agencies (OTAs): Examples include Expedia, Priceline, Orbitz, Travelocity, and Cheaptickets. OTAs can sometimes offer package deals (flights + hotels or rental cars) that are cheaper than booking each component separately. However, be sure to compare the total cost with booking directly with the airline and hotel, as OTAs often add fees.

A Word of Caution about OTAs: While OTAs can sometimes offer lower prices, they can also present challenges when it comes to customer service and making changes to your booking. Dealing directly with the airline is generally easier if you need to change or cancel your flight.

The Power of Flexibility: Dates, Destinations, and Airports

Flexibility is your greatest asset when searching for cheap flights. The more flexible you can be with your dates, destinations, and airports, the higher your chances of finding a great deal.

Date Flexibility

Airlines adjust their prices based on demand, so being flexible with your travel dates can lead to significant savings. Here’s how to leverage date flexibility:

• Use Flexible Date Search Tools: Most flight search engines, including Google Flights and Skyscanner, offer flexible date search options. These tools allow you to view prices for a range of dates, typically a week or a month at a time.
• Travel During the Shoulder Seasons: The shoulder seasons (spring and fall) often offer a sweet spot between peak season crowds and off-season weather. Flights are typically cheaper during these periods.
• Consider Mid-Week Flights: Flights departing on Tuesdays, Wednesdays, and Thursdays are often cheaper than flights departing on Fridays and Sundays.
• Be Open to Red-Eye Flights: Overnight flights (red-eye flights) are often less expensive than daytime flights.
• Adjust Your Trip Length: Sometimes, slightly altering the length of your trip (e.g., staying one extra day) can result in a lower overall flight cost.

Destination Flexibility

If you’re open to different destinations, you can often find amazing deals. Here’s how to leverage destination flexibility:

• Use the “Everywhere” Search: Skyscanner’s “Everywhere” search allows you to enter your origin airport and see a list of the cheapest destinations to fly to.
• Consider Alternative Airports: Flying into a smaller or less popular airport near your desired destination can sometimes save you money.
• Be Open to Unexpected Destinations: Sometimes, the best travel experiences come from visiting places you hadn’t initially considered.

Airport Flexibility

Similar to destination flexibility, flying into or out of alternative airports can significantly reduce your flight costs. This is especially true if you live in a metropolitan area with multiple airports.

• Research Nearby Airports: Before booking, research all the airports within a reasonable distance of your origin and destination.
• Consider the Cost of Transportation: Factor in the cost of transportation (e.g., train, bus, taxi) to and from the alternative airport when comparing prices.
• Weigh the Convenience Factor: While saving money is important, also consider the convenience of flying into a more accessible airport.

Utilizing Flight Deal Websites and Newsletters

Several websites and newsletters specialize in finding and sharing flight deals. These resources can save you a significant amount of time and effort by curating the best deals from across the web.

• Scott’s Cheap Flights (Going): This service sends email alerts when cheap flights are available from your departure airport. They offer both a free and a premium subscription. The premium version offers more personalized alerts and access to even better deals.
• The Flight Deal: This website posts daily flight deals, focusing on error fares and heavily discounted tickets.
• Secret Flying: Similar to The Flight Deal, Secret Flying shares flight deals and error fares.
• Airfarewatchdog: Airfarewatchdog lists flight deals and allows you to set fare alerts.
• Travelzoo: Travelzoo features deals on flights, hotels, and vacation packages.

Pro Tip: Sign up for multiple flight deal newsletters to increase your chances of finding a great deal.

Understanding and Leveraging Error Fares

An error fare is a flight ticket that is priced significantly lower than it should be due to a mistake made by the airline or OTA. Error fares are rare, but when they occur, they can offer incredible savings. Here’s what you need to know about error fares:

• They Don’t Last Long: Airlines are quick to correct error fares, so you need to act fast when you find one.
• Book Directly with the Airline: To minimize the risk of cancellation, it’s generally best to book error fares directly with the airline.
• Don’t Call the Airline: Calling the airline to confirm the fare could alert them to the error and prompt them to correct it.
• Wait Before Making Other Plans: It’s wise to wait a few days to ensure that the airline honors the ticket before making other non-refundable travel arrangements (e.g., booking hotels or tours).
• Be Prepared for Cancellation: Airlines are not obligated to honor error fares, and they may cancel the ticket. If this happens, you’re typically entitled to a refund.

The Best Time to Book: Debunking the Myths

There’s a lot of conflicting information about the best time to book flights. While there’s no magic formula that guarantees the lowest price, some general guidelines can help you increase your chances of finding a good deal.

The “Sweet Spot”: The generally accepted “sweet spot” for booking flights is:

• Domestic Flights: 1 to 3 months in advance.
• International Flights: 2 to 8 months in advance.

Avoid Booking Too Early or Too Late: Booking too far in advance (e.g., more than a year) or too close to your travel date (e.g., within a few weeks) is generally not advisable. Airlines tend to price flights higher during these periods.

Tuesday Afternoon Myth: The long-held belief that Tuesdays are the best day to book flights is largely a myth. While it’s true that airlines sometimes release sales on Tuesdays, the price fluctuations are often minor and unpredictable. Focus on searching for flights regularly and using price tracking tools rather than relying on this outdated tip.

Secret Strategies and Hidden Tactics

Beyond the standard tips, several lesser-known strategies can help you unlock even greater savings on your flights.

The Hidden City Ticketing Strategy

Hidden city ticketing involves booking a flight with a connection in your desired destination, but you disembark at the connection point instead of continuing to the final destination. For example, if you want to fly from New York to Chicago, you might book a flight from New York to Denver with a connection in Chicago, and then simply get off the plane in Chicago.

Important Considerations:

• Only Works with One-Way Tickets: This strategy only works with one-way tickets, as the airline will cancel the remaining segments of your itinerary if you miss a flight.
• Don’t Check Luggage: You can’t check luggage with hidden city ticketing, as your luggage will be routed to the final destination on your ticket.
• Risk of Cancellation: Airlines are increasingly cracking down on hidden city ticketing, and they may cancel your ticket if they suspect you’re engaging in this practice.
• Potentially Violates Airline Rules: This practice may violate the airline’s terms and conditions, which could result in penalties.

Ethical Considerations: Hidden city ticketing is a controversial practice. While it’s not illegal, some consider it unethical because it circumvents the airline’s pricing policies.

Booking Separate One-Way Tickets

Sometimes, booking two separate one-way tickets (one for your outbound flight and one for your return flight) can be cheaper than booking a round-trip ticket. This is especially true when flying with different airlines or when taking advantage of special one-way fares.

How to Do It: Use a flight search engine that allows you to search for one-way tickets separately. Compare the total cost of booking two one-way tickets with the cost of booking a round-trip ticket.

Using VPNs (Virtual Private Networks)

Some travelers believe that using a VPN to change your apparent location can sometimes result in lower flight prices. The theory is that airlines may charge different prices based on the country where you’re booking the flight.

Does It Work? The effectiveness of this technique is debated. Some travelers have reported success using VPNs, while others haven’t seen any difference in price. It’s worth experimenting with different VPN locations to see if it works for your desired route.

Clearing Your Browser Cookies and Cache

Airlines and OTAs sometimes use cookies to track your browsing activity. Some travelers believe that clearing your browser cookies and cache before searching for flights can help you avoid seeing inflated prices based on your previous searches.

How to Do It: Clear your browser’s cookies and cache regularly. You can usually find this option in your browser’s settings menu.

Loyalty Programs and Credit Card Rewards

Joining airline loyalty programs and using travel rewards credit cards can be a great way to earn points or miles that you can redeem for free or discounted flights.

Airline Loyalty Programs

Most major airlines offer loyalty programs that allow you to earn miles for every flight you take. You can also earn miles through other activities, such as using an airline-branded credit card or shopping with partner merchants. The miles can then be redeemed for free flights, upgrades, or other travel benefits.

Tips for Maximizing Airline Loyalty Programs:

• Choose a Program That Aligns with Your Travel Habits: If you frequently fly with a particular airline, focus on earning miles with that airline’s loyalty program.
• Take Advantage of Bonus Mile Offers: Airlines often offer bonus miles for signing up for their credit cards or for completing certain activities.
• Redeem Your Miles Wisely: The value of your miles can vary depending on how you redeem them. In general, redeeming miles for flights offers the best value.

Travel Rewards Credit Cards

Travel rewards credit cards allow you to earn points or miles for every purchase you make. These points or miles can then be redeemed for flights, hotels, or other travel expenses. Some cards offer sign-up bonuses that can be worth hundreds of dollars in travel.

Types of Travel Rewards Credit Cards:

• Airline-Branded Credit Cards: These cards are affiliated with a specific airline and offer benefits such as bonus miles, free checked bags, and priority boarding.
• General Travel Rewards Credit Cards: These cards offer points or miles that can be redeemed for travel with any airline or hotel.

Choosing the Right Travel Rewards Credit Card:

• Consider Your Spending Habits: Choose a card that offers bonus points or miles for the types of purchases you make most frequently.
• Evaluate the Redemption Options: Make sure the card offers redemption options that align with your travel goals.
• Pay Attention to Fees and Interest Rates: Choose a card with reasonable fees and interest rates. Pay off your balance in full each month to avoid paying interest charges.

The Art of Patience: Monitoring Prices and Booking at the Right Time

Finding cheap flights often requires patience and persistence. Don’t expect to find the perfect deal on your first search. Instead, monitor prices regularly and be ready to book when the price is right.

Using Price Tracking Tools

Price tracking tools can help you monitor the price of a specific flight or route and receive email alerts when the price changes. This allows you to track price fluctuations and book your flight when the price drops to your desired level.

Popular Price Tracking Tools:

• Google Flights Price Tracking: Google Flights allows you to track prices for specific flights or routes and receive email alerts.
• Kayak Price Alerts: Kayak offers a price alert system that notifies you when prices drop for your desired flight.
• Skyscanner Price Alerts: Skyscanner also provides price alert functionality.

Booking During Sales and Promotions

Airlines frequently offer sales and promotions to fill empty seats. These deals can be a great way to save money, but they’re often time-sensitive.

How to Find Sales and Promotions:

• Sign Up for Airline Email Lists: Receive email alerts about upcoming sales and promotions.
• Follow Airlines on Social Media: Airlines often announce sales and promotions on their social media channels.
• Check Flight Deal Websites: Websites like Scott’s Cheap Flights and The Flight Deal often feature sales and promotions from various airlines.

Navigating the Booking Process: Avoiding Common Mistakes

Even after finding a cheap flight, it’s important to navigate the booking process carefully to avoid making costly mistakes.

Double-Check Your Information

Before finalizing your booking, carefully double-check all the information you’ve entered, including your name, date of birth, passport number, and flight details. Even a small error can result in problems at the airport.

Be Aware of Baggage Fees

Airlines often charge extra for checked baggage and sometimes even for carry-on baggage. Be sure to check the airline’s baggage policy before booking your flight to avoid unexpected fees. Consider using a credit card that offers free checked bags as a benefit.

Read the Fine Print

Before clicking “book,” take a moment to read the fine print, including the cancellation policy and any other terms and conditions. This will help you understand your rights and responsibilities in case you need to change or cancel your flight.

Consider Travel Insurance

Travel insurance can protect you against unexpected events that could disrupt your trip, such as flight delays, cancellations, medical emergencies, or lost luggage. Consider purchasing travel insurance to protect your investment.
