Traveling is a lot of fun, but some expenses, like airfare, can take up a significant portion of your vacation budget. You can better honor your budget by opting for economy class tickets. But which airlines are best for flying in coach? Let's take a closer look at the top airlines for economy class.

Best airline for value: Southwest Airlines

Southwest is known for charging minimal fees, which can be a win if you're a traveler who books economy class airfare tickets. The airline doesn't charge change or cancellation fees as long as you cancel your flight at least 10 minutes before the scheduled departure.

Southwest also allows every flier to bring two checked bags for free. Extra bag fees can add up, especially when traveling with companions. These additional perks can provide value to travelers.

Here's one pro tip I'd like to share if you're working with a limited budget: Try to buy your airfare during one of Southwest's sales. The carrier runs sales several times a year. This strategic move could help you keep more money in your checking account.

Best airline for basic economy: American Airlines

Basic economy tickets are the most affordable economy tickets available. However, this fare has more restrictions. However, it can be a great option if you need to buy airfare without racking up an expensive credit card bill.

American Airlines is the winner for this category. Compared to other U.S.-based airlines, the carrier includes more perks with its basic economy fare. For example, you can bring a personal item and a carry-on bag. United fliers with a basic economy ticket can't bring a carry-on bag for free on most domestic routes.

Finally, you can earn AAdvantage miles when flying on a basic economy ticket. You'll earn fewer miles than flying on a main cabin ticket, but will still get rewarded. Review the restrictions before booking basic economy tickets with American Airlines for the best success.

Best airline for seat comfort when flying economy: JetBlue Airways

Flying on an economy ticket is almost always more affordable than flying on a premium-class ticket. But it's not exactly the most comfortable experience. But if you're selective about which airline you fly with, you can improve your comfort and overall travel experience.

When comparing U.S.-based carriers, JetBlue stands out as a winner in terms of seat comfort. The airline offers basic economy tickets (Blue Basic) and economy tickets (Blue), so there are options for low-cost fares.

A recent study from Upgraded Points found that JetBlue has an average seat pitch of 32.3 inches -- earning a top spot above all other major U.S. carriers. The exact seat pitch and legroom vary by plane, so you'll want to review these details before you book a ticket. The tool aeroLOPA is excellent for viewing accurate seat maps for each carrier's fleet.

JetBlue has Even More Space seats available for an additional fee if you want to improve your comfort more by selecting a seat with more legroom -- up to 38 inches. But only upgrade your seat if it fits your budget. It's not worthwhile to go into debt for more legroom.

Consider your needs and budget before buying airfare

If you need to buy airfare for an upcoming trip, booking economy class is an excellent strategy to avoid overspending. However, keep in mind that not all airlines are created equal.

Some airlines may be a better choice if you prefer a value-packed experience or greater comfort. Consider your budget and travel needs before booking a flight so you can choose an ideal airline. It's also smart to carefully review the terms before booking a ticket.

Consider the best payment method to use at checkout, too. Using one of the best travel credit cards could allow you to earn valuable rewards on your spending. You can redeem your rewards for nearly free travel in the future.
