Question: I plan on booking a first-class Lufthansa ticket, IAD-FRA-AMS, through Lifemiles.
On the day of departure, does anyone have experience changing the time of the flight FRA-AMS at the Lufthansa check-in desk in IAD or the first-class lounge in FRA? In other words, will Lufthansa be able to change my flight time for my connection FRA-AMS to a later flight?
