On April 21 we flew from Tampa, FL to Florence. We booked with Lufthansa but were switched to EW Discover (a Lufthansa partner) from Tampa to Frankfurt. In Frankfurt, when checking in at the gate to board our ongoing flight to Florence, our boarding passes were rejected and we were told that we had been rebooked on Austrian Air to Vienna and then on another Austrian Air flight to Florence. We were, to say the least, shocked. (I want to use stronger language but that would violate the rules of this Forum!) We had no idea that the boarding passes we were issued in Tampa for the Frankfurt to Florence flight would not be valid. Has anyone else had a similar experience? I will be loathe to book international flights with Lufthansa in the future.
BTW they also did not ask for our CDC cards before boarding, nor the PLF, and did not utilize our Global Re-entry number so that we were not TSA Preapproved.
