We booked first class seats to/from (SFO) to Omaha, Nebraska. Flew home today (September 23, 2019) and had a terrible experience. We have flown first class on numerous airlines (Alaska, Hawaiian Air, Virgin, etc) .... and have always had great experiences. First off, we had terrible turbulence --- but that we NOT United's fault for sure. With already short nerves (due to the non-stop bumpy ride), we had a trainee stewardess (again, not their fault)... BUT the gal that was mentoring her NEVER STOPPED TALKING!!! We were in row 2 -- and she sat up front talking to the trainee the ENTIRE TIME -- loudly!!! By the time our 3+ hour flight was up, we could become flight attendants ourselves! And - to top that off, the trainee NEVER even came and asked if we wanted drinks or snacks - or even picked up our trash (until right before we landed). When we pay a fortune for first class tickets - we would expect MUCH BETTER service than that! United --- wake up!!! Train your attendants to provide the excellent service that you claim you offer! I'll look for other airlines to travel back and forth in the future!
