- Checked bags, carry-on size enforcement, seat assignments (if you need them), change risk, and card/payment fees.
- Mechanically similar — both unbundle — but LCC fee menus are often more aggressive and airport gate prices hurt more.
- Verdict: never rank fares on base alone. Not for packing for a Basic ticket as if it were legacy standard.
