Airline fee and baggage policy pages
Start with the airline, then move into the fee guide or calculator that matches your trip. The strongest pages explain carry-on rules, checked-bag charges, seat fees, change rules, and the places where fare restrictions can make a cheap ticket more expensive.
Start with the cost decision
Across 81 airline pages, use these checks to find when the cheapest ticket stops being the cheapest trip.
Count travelers, bags, and directions, then check whether the exact fare already includes an allowance.
Compare checked-bag rulesCompare outside dimensions—including wheels, handles, and pockets—with the airline's published limit.
Check sizer riskThe lowest fare may not be cheapest after a bag, seat choice, or change flexibility is included.
Check cheap-fare restrictionsIf you know the airline
Open its airline page first, then move into the bag calculator, sizer guide, or Basic Economy guide based on the trip.
If you will check bags more than once
Price the bags first, then run the card break-even calculator only if the annual savings could beat the fee.
Run card break-evenPriority U.S. and low-cost comparisons
Start here when baggage, a stripped fare, or an unbundled low-cost model is likely to change which flight is actually cheaper.
Compare Basic Economy restrictions, checked-bag costs, and the value of moving to a less restrictive fare.
Check how the fare, route, bag number, and eligible card or status benefit change the baggage total.
Separate the published bag price from route exceptions, fare rules, and excess-baggage exposure.
Check the current included allowance and fare benefits instead of relying on the airline's former baggage policy.
Compare fare-level baggage treatment and any eligible card benefit before assuming the lowest fare wins.
Check ticketing date, route exceptions, Saver treatment, and eligible card or status benefits together.
Price the personal-item limit, overhead bag, seat, and bundle before comparing its headline fare.
Separate the free small personal item from paid cabin-bag access and airport handling charges.
Compare the included under-seat bag with large-cabin-bag access through a seat, bundle, or separate purchase.
International baggage rules to check carefully
These airlines often need extra context because checked baggage can depend on route, cabin, fare family, and whether the itinerary uses a piece or weight allowance.
Check whether the exact Basic itinerary includes an overhead bag and how route and fare brand affect checked baggage.
Use the ticket and itinerary allowance first; additional-bag pricing is not one universal amount.
Distinguish short-haul Economy Basic from fares that include an overhead bag, then check route-specific baggage rules.
Identify the applicable piece or weight concept before treating any published allowance as universal.
Separate domestic and international baggage rules, weight allowances, and route-specific excess charges.
Check long-haul versus within-Asia allowances and the current prepaid excess-baggage conditions.
Check the booked fare and operating carrier before relying on the cabin or checked-bag allowance.
Use the fare and itinerary because included bags and additional-bag prices can vary by trip.
Confirm whether the itinerary uses a weight or piece allowance before calculating extra baggage.
Check route, cabin, and the applicable piece or weight system before comparing allowances.
