Poor|Aug 2025

Our flight kept getting delayed due to the weather and mechanical issues. Then it was canceled and rescheduled until the following day which was also delayed by a couple hours and the returning flight was also delayed so overall, we wasted a lot of time on the airport. Also, when it happened the first day, they did not want to honor a hotel or rideshare service voucher because it was hard to find an uber at 3-4 in the morning and customer service was closed that late in the day.

I have no complaints about my flight to and from Munich from Charlotte NC. Everyone was helpful and courteous. I will definitely fly with you all again!

Was wrongly scheduled and had to rebook in another flight with a different carrier at a higher cost. The entire initial booking experience was horrible.
