I have a 2-leg flight (through Frankfurt) booked with Lufthansa, return ticket (Economy Basic). The travel agent has informed me that the rebooking fee is 70 EUR.
Is this per leg, or per flight, or per ticket? For example, if I want to change both the departure and return dates, do I pay 70, or 2x70 (or is it, perhaps, 4x70 - they charge extra baggage per leg, and for both ways)
