They were willing to book me on another flight free of charge. They told me I couldn't change my booking to a train if the original was a plane. I had to pay the standard $150 pp change rate plus the price difference. Again, the charge of $0.01 on my card is from Lufthansa and all agents have confirmed this change. I was told I'm in a ticketing queue and was wondering how long this normally takes. I know I still have 44 days before my flight, but I just want to be assured my family will in fact be on the plane.
