Find the airline fee that changes your trip cost
Start with the charge your trip is likely to trigger—not a generic airline list. Each topic combines official source records with the fare, route, timing, and traveler conditions that determine whether the fee applies.

Start with the decision
What are you trying to prevent?
A cheap fare becoming expensive
Compare advertised fares after adding the bags, seats, travelers, and directions the trip actually needs.
A bag failing the published limit
Compare the bag's outside dimensions with published carry-on and personal-item rules.
A restricted fare creating add-ons
Test whether the savings survive baggage, seat, and flexibility restrictions.
Baggage decisions
Begin with the normal allowance, then check whether weight, size, item type, or purchase timing creates another charge.
Checked baggage
Calculate the party-level, round-trip cost and check whether the fare already includes an allowance.
Carry-on and personal items
Separate free under-seat entitlement from overhead-bin access, then check size, weight, and timing.
Overweight baggage
Check the airline's weight bands and maximum before an airport repack becomes the only practical option.
Oversize baggage
Determine whether the size charge stacks with the normal bag fee and whether the item is accepted at all.
Sports equipment
Check whether the item uses the normal allowance, a special fee, or airline-specific handling limits.
Fare add-ons and flexibility
These charges are often consequences of the fare chosen, so compare the restriction with the cost of buying a better fare.
Seat selection
Decide whether the charge buys a meaningful seat benefit or merely repairs a restrictive fare.
Changes and cancellations
Separate a waived change fee from fare differences, credits, same-day options, standby rules, and nonrefundable value.
Unaccompanied minors
Confirm the age band, whether the service is required, and whether connections are permitted before comparing fares.
