The Simple Way to Fly on the Cheapest Airlines

If you're traveling by air, it's likely that the cost of the airline is a factor in your travel choices. But what are the cheapest airlines in the United States and how can you be sure you're getting the best available airfare? DoNotPay can help you find the cheapest airlines and even find discounts on the already-low fares.

How to Save Money on Airline Tickets on Your Own

There are a variety of ways to save money on airline tickets, even when you're not flying on the cheapest airlines.

• The first tip for saving money on airfare is to be flexible with your travel plans. If you can, book your flights for weekdays. Tuesday and Wednesday tend to be the cheapest days to fly, according to Airfare Watchdog. Fridays and Sundays, on the other hand, tend to be the most expensive days to fly, so you should avoid them whenever possible.

You may also consider booking a red-eye flight since many airlines have trouble filling seats on flights that depart late at night, you can often find great deals there. Finally, consider flying into a smaller, nearby airport (such as Chicago's Midway airport instead of O'Hare). This can make air travel both cheaper and more pleasant for you.

• Another way to save money on airline tickets is to book your flight early. Flights are cheapest if you book them between four months and three weeks before your travel date; the closer to your travel date, the more expensive the tickets get.
• Also consider booking a pair of one-way flights instead of a round trip. This allows you to mix and match airlines for your trip, as well as taking advantage of promotions in multiple ways.

What Airlines Offer Coupon/Promo Codes?

Most airlines offer occasional promotions on their websites, but they're often hidden and hard to find. Some of these promotions require you to book through a specific vendor, or stay a certain length of time, but it's always worth taking a look before you book your flight!
