How baggage fee calculator Works
The three fee regimes
Budget carriers unbundle everything: checked bags $35–60, carry-ons sometimes charged, airport payment premium. Legacy domestic charges $35 first/$45 second with steep thirds. Full-service international typically includes one or two checked bags — where the fee regime started before domestic unbundling spread.
The channel discount
Paying at booking or online check-in runs $5–15 cheaper per bag than the airport counter — the airlines' nudge toward predictable operations. The habit is simple: add bags to the booking, or prepay during online check-in, and the counter becomes a drop-off.
The redistribution play
Third bags price 3–4× first bags. A family of four with five bags does better checking 8 bags across 4 people (first-bag rates) than 5 bags with thirds. Redistribute before you pay — the fee table rewards even distribution mathematically.
