Flight from Denver to Philadelphia

PaulFlew with American AirlinesDEN-PHLJan 2025

Contour airlines was great for a connection through Philadelphia. I had a tight connection and thought I might not make it, but I called and was able to talk with an actual person. They called ahead to the gate, and the plane held the door open a few minutes for me. Great service, and a very comfortable flight.

Don’t fly frontier. The staff at the airport is rude, be careful.
