Basic Economy vs. Main Cabin: What’s The Difference?

Basic economy fares can be significantly cheaper than main cabin tickets, but these bare-bones tickets usually come with meaningful trade-offs, including major constraints on seat selection, changes, cancellations, upgrades and mileage earning.

What's more, each airline handles basic economy fares differently, including how they name them, so your experience may vary. But depending on your situation, budget and travel preferences, the cost savings could be worthwhile. Here's how to decide whether it's beneficial enough for you.

Price differences between basic economy and main cabin tickets

The premium for main cabin tickets varies and depends on the airline you're flying, the route and even when you book your flight. To give you a general idea of what to expect, we compared prices for three domestic round-trip routes for several major airlines. Here's the average difference for each one:

Delta had the largest price difference, with an average difference of $113. The other airlines were relatively close, ranging from $87 to $90. However, the actual upcharge can fluctuate, and if you're thinking of planning an international trip, you can generally expect the price gap to widen even further.

For Alice Wu, a public relations professional in Ontario, Canada, the savings are virtually always worth it. “I hate spending more than I absolutely have to, so customizing options makes sense,” she said. She also doesn't fly with carry-ons, so there's no need to get on the plane early to find overhead space.

Basic economy rules by airline

No two airlines define basic economy the same way, even down to what they call the no-frills fare. Here's a glance at what you can generally expect with each airline. We'll dive deeper into the features that matter most in the next section.

Major differences between basic economy and economy inclusions

Changes and cancellations

The U.S. Department of Transportation allows travelers to cancel a flight booking within 24 hours without penalty. But after that, airlines might not offer changes or cancellations on their basic economy fares, and if they do, you'll typically get only a travel credit, and you'll often need to pay a fee.

Since most airlines have eliminated change fees on main cabin fares, that makes basic economy fares even more restrictive. "I always have to ask myself how much I'm willing to lose," Wu said.

In some cases, though, you may be able to get around a change fee or a partial refund by upgrading your basic economy ticket to a main cabin fare.

However, the only time this makes sense is if the potential fee and refund savings outpace the cost of upgrading your ticket. In general, it's always best to book a main cabin fare if you think your plans may change.

Seat selection

For all airlines, you generally won't get a seat assignment included with your basic economy ticket, but most of them give you the option to pay to select your seat ahead of time. Otherwise, you'll have to wait until you check in to get your seat assignment.

If the airline assigns your seat after check-in, you're more likely to get stuck in the back of the plane or in a middle seat, and there's no guarantee that you'll be able to sit with your travel companions.

Alaska is the only major airline that doesn't allow seat selection of any kind for its Saver fares. Southwest also won't allow it unless you're an A-List member or have a Rapid Rewards credit card. The other airlines offer more flexibility, but you'll pay for the convenience.

Julien Casanova, a travel expert based in Oaxaca, Mexico, says she flies basic economy roughly 30% of the time, adding that the value of seat selection depends on the situation. "I choose basic economy for short flights where you touch down before you can even rest your head or get into listening to a podcast," she said.

For longer flights and itineraries with a short layover, being able to choose a seat in advance is more important. "If I have a tight connection, I choose the main cabin so that I can be one of the first to get off the plane. Even a few minutes can make a difference," she added.

It's worth noting that airlines typically make an extra effort to keep parents and small children together.

In fact, Alaska, American and JetBlue all guarantee that young children will be seated next to at least one accompanying adult at no extra cost, including for basic economy fares, as long as you meet certain conditions. Meanwhile, Delta, Southwest and United will offer assistance, but they stop short of guaranteeing children will be seated with an accompanying adult.

You may be able to count on more help if you have younger children. Wu often flies with her children, and there were a few times when they were just a few years old that the airline split them up. "I just went up to the counter and asked the agent to seat us together since my kids were very young, and they were happy to oblige," she said. "I'm not sure airlines want to be responsible for a three-year-old sitting next to a stranger."

Carry-on bags

Five out of the six major airlines let basic economy passengers bring a full-size carry-on plus a personal item, so if you're planning a quick trip, a basic economy fare may be good enough.

The only outlier is United Airlines, which doesn’t include a complimentary carry-on bag unless you're flying to South America, across the Atlantic or to other international destinations across the Pacific.

But if you're flying with a different airline and having a carry-on allowance is your top priority, there isn't much difference between basic economy and main cabin.

Miles and elite status

Mileage earning on basic economy has been gutted in recent years, making it unappealing for travelers looking to rack up redeemable miles and credits toward elite status. However, there are some exceptions, depending on who you're flying with.

Half of the major airlines award nothing on their cheapest fares, including progress toward elite status (with the one exception for Atmos Million Miler status). If you're chasing status or looking to accumulate miles for your next trip, a basic economy ticket with one of those airlines is a dead end.

Even with the airlines that do still offer redeemable and elite-qualifying rewards, you can expect a reduced earnings rate compared with a main cabin ticket.

When to choose basic economy

The logic of basic economy from the airlines’ perspective is simple: They want to entice you with low fares in search results and then make the experience unappealing enough that you'll want to pay to upgrade your ticket to a more expensive fare.

This setup creates an opportunity for any budget-conscious traveler, but it's not always a clear-cut choice. Should you save the money on the ticket price and lose some privileges, or pony up the cost to “upgrade” your ticket to the main cabin?

Here’s a good rule of thumb for when to choose basic economy:

• Your plans are firm (not "probably fine," but absolutely firm).

• You are traveling alone, or you're traveling with a companion who doesn't mind sitting separately.

• You don’t care about earning points and elite status.

• You don't fly with the airline often enough to make any redeemable rewards or elite credits you might earn relevant.

• You don’t mind where you sit (or at least, you’re willing to deal with the middle seat if it means saving money).

• If you're flying with Delta or JetBlue, you're not planning to hit the Sky Club or BlueHouse lounge.

If that doesn’t sound like you, consider booking a main cabin fare.
