FAQ
- How do I compare carry-on size across airlines?
- Use the carry-on size hub for a side-by-side table, then open the airline page for wheels/handles, Basic fares, and regional-jet gotchas.
- Where are baggage fees?
- The baggage fees hub summarizes personal item, carry-on free vs paid, and typical domestic first-checked amounts when published. Dynamic carriers say Dynamic — see airline page.
- What’s the personal item hub for?
- Under-seat bag dimensions — or Under seat / not published when the airline does not give L×W×H.
- Why isn’t Spirit listed?
- Spirit Airlines ceased operations in 2026. BagRule only publishes the 12 allowlisted US brands on this index.
- Do these pages replace the airline site?
- No. Bag rules change. Confirm size, fee, and fare rules on the airline site before you fly.
