Even though the flight was delayed for 2 hours due to maintenance the flight was good. Thank you for giving us the option to leave the plane during the delay.

I had to change flights at.the last minute because of maintenance delays; customer service at the St. Louis airport was very helpful.

They were a bit rude with booking carry on to final destination only. Would have preferred gate check on first leg of international flight

As I was waiting for boarding to begin, I noticed an airline employee approach people about the size of their bags...that there would be a problem due to size. I wish someone had approached me last year BEFORE I entered the plane. When I purchased it I had been told my bag would fit under the seat, but as soon as I boarded the attendant was right there grumpily telling me it had to go in the overhead and oh, by the way, there isn't any room because the flight was booked full. How embarrassing! Better to be approached in the gate waiting area.
