What You Can Carry On in Basic Economy, Airline by Airline

As of November 2026, a Basic Economy ticket includes a full-size carry-on bag on Delta, American, Alaska, JetBlue and Southwest, but on United domestic flights and on Frontier's base fare it covers only a personal item. American confirmed in its April 9, 2026 release that Basic Economy includes "one free personal item and one free carry-on bag". Spirit is not in the comparison because it stopped flying on May 2, 2026.

The sections below give each airline's rule, the exceptions, what is known about gate-check charges, and a worked example of when the cheaper fare stops being cheaper.

Key takeaways

Delta, American, Alaska, JetBlue and Southwest each list a carry-on and a personal item as included on their lowest fare.
United's domestic Basic Economy is reported to allow only a personal item, with exceptions for elite members and qualifying cardholders. United's own pages could not be opened for this article, so that row rests on two dated third-party reports.
Frontier's base fare includes a personal item only; a carry-on is an add-on or part of its Economy bundle.
Allowing a carry-on does not guarantee bin space. Basic fares usually board last, and Delta and JetBlue both say bin space can run out.
In the worked example, a $90 round-trip saving turns into a $30 loss when the bag is paid for at the gate, with a $25 handling charge, instead of ahead of time.

What it means for you

Packing only a backpack or purse: every Basic fare in the table works; check the personal-item size limit for your airline.
Need a roller bag: Delta, American, Alaska, JetBlue and Southwest include it. On United and Frontier, price the bag before choosing Basic (see the break-even section).
Travelling with children: seat selection, not the carry-on, is the bigger risk on Basic; see the seating notes below.

Basic Economy carry-on by airline

Every row comes from the airline's own page except United, which is marked. Fare names differ: Delta calls it Main Basic, JetBlue Main Base, Alaska Saver. Check the fare screen at purchase, because rules can differ by ticket date and route.

Airline and fare	Full-size carry-on	Personal item	Gate check and notes
Delta Main Basic	Included; one bag up to 22 x 14 x 9 inches (Delta carry-on page)	Included	Boards in Zone 8, so bins may fill; a carry-on gate-checked for lack of space is free (Delta agency page, updated Nov. 19, 2025)
American Basic Economy	Included, one free bag (April 9, 2026 release)	Included, one free item (same release)	Stated in American's April 9, 2026 release; the release gives no gate-check charge
Alaska Saver	Included, same carry-on allowance as Main	Included	Boards last in group F; bin space is first come, first served (Alaska Saver page)
JetBlue Main Base	Included; up to 22 x 14 x 9 inches, space permitting	Included; up to 17 x 13 x 8 inches, under the seat	Boards in the General group (JetBlue fares page)
Southwest Basic	Included; one carry-on within 10 x 16 x 24 (the fee page prints no units)	Included; one smaller item such as a purse, briefcase or backpack	Checked bags cost $45 (first) and $55 (second) on Basic (Southwest fee page); Basic is last to board (fare types page)
Frontier base fare	Not included; add one (up to 24 x 16 x 10 inches, 35 lb) when booking, or buy the Economy bundle	Included; up to 18 x 14 x 8 inches and 35 lb	A personal item over the limit is "subject to an additional charge" (amount not stated), and bags bought at the airport cost more. A paid carry-on that finds no bin space may be gate-checked at no extra cost. The Premium bundle adds Board First (Frontier bag page)
United Basic Economy (domestic)	Reported not included, except for exempt travelers (both reports in the last column)	Included; 9 x 10 x 17 inches, per Upgraded Points (June 10, 2026) only	Reported: a full-size bag brought to the gate is checked for the checked-bag fee plus a $25 gate handling charge (Upgraded Points, updated June 10, 2026; One Mile at a Time, updated Dec. 27, 2025)

United exceptions, with a caution

United's own pages could not be loaded for this article, so this section rests on two travel-site reports. Both say a Basic Economy traveler may bring a full-size carry-on with MileagePlus Premier status (Silver, Gold, Platinum or 1K) or Star Alliance Gold status. One Mile at a Time words the card exemption as the primary cardmember on a qualifying United credit card who bought the ticket with that card. Only Upgraded Points says that companions on the same reservation may qualify if space permits, that the restriction does not apply on transatlantic, transpacific or South American routes, and that a bag gate-checked on a United Express flight carries no fee. Confirm each point on united.com or in the booking confirmation before relying on it.

Spirit is no longer an option

Spirit began what it called an "orderly wind-down of our operations, effective immediately" on May 2, 2026, NPR reported. One Mile at a Time put the stop at 3 a.m. Eastern that day. It is omitted from the table.

Seats, changes, boarding and miles

The carry-on is the part most Basic fares keep. The cuts come elsewhere, and the figures below are from the same pages as the table. "Not confirmed" means the pages checked did not state it, not that the feature is included.

Fare	Seat	Change or cancel	Miles
Delta Main Basic	Paid selection from 30 days to 24 hours before departure; otherwise assigned after check-in or at the gate; travel companions may not be seated together	No cash refund after the risk-free window, and no same-day changes. Cancel before departure for an eCredit minus $99 (most US, Canada and nearby routes) or $199 (most long-haul trips from the US), per the agency page. Delta's pages differ on changes: its change and cancel overview lists a $0 to $400 change fee plus any fare difference for Basic tickets, and cancellation charges of $99 to $500 across its Basic fares, while its cancel page says Basic tickets cannot be changed or refunded after the 24-hour risk-free period. Read the fare rules at purchase	None
American Basic Economy	For tickets bought from May 18, 2026, everyone including status members pays to choose a seat (April 9, 2026 release)	Not confirmed; American's fare page could not be opened for this article	Not confirmed; per the same release, tickets bought from May 18, 2026 lose complimentary and systemwide upgrades
Alaska Saver	Assigned at check-in; no guarantee that a party of two or more sits together	50% credit if canceled 14 or more days before the first flight; same-day confirmed change for a fee when eligible; other changes not allowed	None if booked after June 11, 2026 for travel on or after Aug. 1, 2026
JetBlue Main Base	Fee to choose; otherwise assigned before departure	Change fee $150 per person plus any fare difference; cancellation gives travel credit minus the fee, valid 12 months from ticketing	1 point per $1, plus 1 more if booked on jetblue.com or the app
Southwest Basic	Standard seat assigned at check-in (at check-in or at the gate for families); A-List and A-List Preferred members and some cardmembers can choose earlier	Changes only by upgrading to Choice or higher; credit expires 6 months after the fare was booked; cancel at least 10 minutes before departure	2x Rapid Rewards points per dollar

Families and seat assignment

The Department of Transportation proposed a rule, published on August 9, 2024, that would require airlines to seat children 13 and under next to an accompanying adult at no extra charge. CBS News reported that it would apply when adjacent seats are available at booking. As of November 2026, the Federal Register lists only that proposal and an October 2024 extension of the comment period, with no final rule, so airline policy still decides.

Southwest says it will "work to seat children ages 12 and younger next to at least one adult" in the party, and that families on Basic get seats at check-in or at the gate (Southwest assigned seating page). Delta's agency page says Main Basic passengers travelling together may not be seated together. Check the airline's family-seating policy before booking a family on Basic.

When a roller bag erases the saving

This matters where a roller bag is not included. On Frontier's base fare it means buying the carry-on add-on. On United domestic Basic, the reports describe no carry-on add-on: the bag is checked, and if it reaches the gate, a $25 handling charge is reported on top of the checked-bag fee. Illustrative example with assumed numbers: Basic is $45 cheaper each way than Main Cabin, and the bag costs $35 each way when paid for ahead of time (a Frontier carry-on add-on, or a checked bag on United). Fees differ by airline, route and date, so substitute the amounts on your fare screen.

Basic saving = (Main fare - Basic fare) x trips
Bag cost     = (bag fee + gate charge) x trips
Net          = Basic saving - Bag cost

Main fare, Basic fare — the two prices per direction
bag fee — what the airline charges to take the bag when you pay ahead: a carry-on add-on, or a checked-bag fee where no carry-on is sold
gate charge — any extra charge if the bag is only dealt with at the gate (0 when paid ahead)
trips — number of flights, 2 for a round trip

Round trip: the saving is $45 x 2 = $90. Paying $35 ahead each way costs $70, so Basic is still $20 cheaper. If the bag is instead taken at the gate and a $25 handling charge comes on top of the $35 each way, the cost is $60 x 2 = $120, and Main Cabin is $30 cheaper. The break-even is a bag cost of $45 per direction, equal to the fare gap; any higher and Main wins.

One bag can wipe out the gap between Basic and Main, and paying at the gate costs more than paying ahead. Only the $25 gate charge comes from the United reports; the other amounts are assumptions. The example leaves out seat fees, which can add more on Basic.

Frequently asked questions

What counts as a personal item on Basic fares?

It is the smaller bag that fits under the seat in front of you, and the limit varies. JetBlue lists 17 x 13 x 8 inches, and Frontier lists 18 x 14 x 8 inches and 35 lb. Upgraded Points reports 9 x 10 x 17 inches for United. Measure against your own airline's current limit before you leave.

Will Delta make me pay if my carry-on is gate-checked?

No. Delta's agency page says checked-bag fees do not apply to carry-ons gate-checked on a Main Basic ticket. Because Main Basic boards in Zone 8, a full bin is a real possibility. On Delta Connection flights with 50 or fewer seats, Delta's carry-on page says only personal items go on board, and larger carry-ons are tagged and gate-checked free.

Can I get a refund on a Basic ticket?

Mostly no. Delta says Basic tickets are nonrefundable, apart from a risk-free window for qualifying eTickets bought directly from Delta for trips that start in the United States. To use it, you cancel by midnight the day after purchase or by midnight on the first flight's departure date, whichever comes first. After that, Delta's cancellation gives an eCredit minus a fee, not cash. Alaska gives a 50% credit when you cancel 14 or more days ahead, and Southwest gives a credit that expires 6 months after booking.

Can I upgrade a Basic fare to get more?

It depends on what you want. Southwest lets Basic customers change a flight only by upgrading to Choice or higher. Delta says Main Basic tickets are not eligible for paid or complimentary upgrades, and American's April 2026 release says Basic tickets bought from May 18, 2026 are not eligible for complimentary and systemwide upgrades. Alaska says Saver passengers can upgrade to Premium or First Class in advance, and paid seats are then nonrefundable.

Do Basic fares earn miles?

It varies. Delta Main Basic earns none, and Alaska Saver earns none when booked after June 11, 2026 for flights from August 1, 2026. JetBlue gives 1 point per dollar plus 1 for booking online, and Southwest gives 2x points per dollar.

Before you pay for Basic

Decide whether you need a bag beyond a personal item, and for how many travelers.
On United and Frontier, add the bag fee for each direction (a carry-on add-on on Frontier, a checked bag on United) to the Basic price and compare with Main.
Check whether status, a co-branded card or an international route gives you a carry-on on that airline.
Add seat fees if you need to sit with a child.
Screenshot the fare rules on the booking screen; rules vary by ticket date and route.
