BEWARE: SWISS strictly enforces cabin baggage allowance
As most of you know, every Y-Class pax is allowed to bring one piece à 8kg, elite members and C-/F- Class pax are allowed to bring two pieces à 8kg (= NOT one piece à 16kg) on board.
I heard that SWISS tries to enforce this rule and especially everyone flying in Y-Class (also elite members) are effected.
