I am really impressed with US's service in IROPS. I frequently fly them because they are cheaper than CO/UA out of/into Memphis. The flight to CLT was delayed on Fri. The agent booked me on a later connection out of CLT. I got to CLT 15 minutes before the scheduled departure of my connection. Landed on concourse C; connection on E. Walked fast, was at the gate about 8 minutes before scheduled departure of original connection. Asked if I could get on. No checked bags. Not a problem. What other airline will let you on 8 minutes before departure, let alone spend the time to change your flight. It meant I didn't have to spend 3 hours in CLT. Despite all the negatives I read about US on FT, I really like them. Now, I haven't flown them for long haul or overseas.
