Questions

Are these baggage fees accurate?

They're each airline's published Economy figures, verified 2026-06. Baggage fees change often — US carriers all raised checked-bag fees in April–May 2026 — so always confirm with your airline before you fly. Fees also vary by route, fare type and when you buy.

Why is the carry-on weight sometimes blank?

Most US carriers don't actively weigh carry-ons, so no limit is shown. European, Gulf and Asian carriers do enforce a cabin weight (often 7–12 kg) — that's shown when it applies.
