SWISS International Air Lines vs Lufthansa carry-on
SWISS and Lufthansa share identical Lufthansa Group hand baggage limits of 55x40x23 cm at 8 kg, plus a 40x30x15 cm personal item. Both offer two carry-ons in Business and First versus one in Economy, and both strip the free checked bag from their cheapest Economy Light fare on European routes. Economy Basic on short- and medium-haul goes further, removing the carry-on bag entirely (personal item only). The practical difference is route network and hub experience rather than baggage policy. Zurich is generally faster for connections than Frankfurt or Munich, and SWISS still accepts a small garment bag up to 57x54x15 cm that travelers sometimes miss in the fine print.
