I have a reservation MXP-MUC-PRG for June which I bought through Expedia. It is a Lufthansa itinerary but the first leg is on Air Dolomiti and the second on Lufthansa Cityline. The confirmation from Expedia says "Please reconfirm your international flight reservation at least 72 hours prior to departure by contacting the airline directly." It also notes: "Your airport check-in is with Air Dolomiti". First question: Do I really have to reconfirm? Most airlines stopped requiring this years ago. Second question: If so, do I reconfirm with Lufthansa or Air Dolomiti?
