The cost for the immediate flight fare due to family emergency was greatly appreciated. Thank you!

We thought we were going to miss our connection in Denver and they held the plane for us and we got our luggage! The six of us were very surprised and very happy!

Years ago I stopped flying United because of employee indifference, they just didn’t care. This was a good experience and hopefully their culture has turned around.

Liked that the flight attendant called me “Madame,” not “Honey,” or “Dear.”
