Checked Baggage Fees (2026): Compare the Same Trip

A checked-bag price is useful only with its route, fare, ticket date, bag number and purchase stage. The same airline can charge a different amount for an earlier ticket, Basic fare, second bag, return direction or eligible benefit. Compare the complete trip rather than relying on a single “average bag fee”.

Published examples, checked 25 October 2026

The amounts below are in USD, per person and per direction, for standard bags within the cited policy. They are examples with conditions, not live reservation quotes.

Airline	Published first / second bag example	Conditions to check	Official source
American	$45 / $55 online; $50 / $60 at the airport	Listed US/nearby-region routes under the policy updated 18 May 2026. Basic Economy adds $5 to each fee; applicable ticket and benefit exceptions matter.	Checked bag policy
Delta	$45 / $55	Domestic Delta Main/Comfort without listed exemptions; standard weight/size rules apply. Earlier ticket dates may have lower fees.	Baggage overview and estimate
Southwest	$45 / $55	US mainland Basic/Choice/Choice Preferred in the ticketed/changed-on-or-after-9-April-2026 category, without an applicable benefit. Other fare, date and region rows differ.	Optional Travel Charges
United	Obtain the itinerary quote	Use the actual route, travel details and benefits. This review did not obtain a completed calculator quote.	Checked-bag fee calculator
Frontier	Obtain the itinerary quote	Standard checked bag: 40 lb and 62 linear inches; purchase timing and included benefits affect the price.	Bag Options
Allegiant	Obtain the itinerary quote	Route, flight segment and purchase timing affect the fee; excess weight/size is a separate condition.	Optional services and fees

Do not apply one row's region or date to another. A free-bag benefit must meet the actual reservation's eligibility conditions; a card or membership name alone is insufficient. Check the operating carrier and through-ticket rules on connecting journeys.

Compare two flight offers on the same basis

Record these inputs for each direction:

Departure and destination, operating airline, travel date and ticket date.
Fare or bundle and any benefit actually applicable to every passenger.
Number of checked bags per passenger, packed weight and total outside dimensions.
Price at booking, after booking or at the airport, with currency and quote time.
Whether overweight, oversize, special equipment or route restrictions add charges.

Calculate base fare + required cabin-bag add-on + checked bags + applicable excess charges for the same people and journey. Do not assume a per-direction example is the total return price.

For example, two adults with one standard bag each in both directions have four bag charges. If their applicable quoted fee is $45 each, that part of the trip totals $180. This is arithmetic using a stated assumption, not a quote or recommendation for a particular itinerary.

Weight, size and fee inclusion are different checks

A 45 lb checked bag exceeds Frontier's published 40 lb standard allowance even if it is within another airline's standard. A bag can also pass weight but exceed a linear-size cap. Paying for one checked bag does not remove acceptance limits or buy a second bag.

For the cabin alternative, use the size chart, weight guide and bag checker. CarrySizer's tools do not access your reservation and do not provide a complete live checked-baggage quote. Open the airline source for the final booked allowance and price.

Before paying for baggage

Measure after packing, check both directions, and compare the actual bundle against the individual services you need. Verify benefits in the reservation before treating any bag as free. If the source or fare remains unclear, retain the uncertainty and ask the operating airline; an old average or a bag accepted on a previous flight is not confirmation.
