Loved the staff, boarding and drink options! Wish the comfort of the seat could have been better nevertheless

So awful Unreliable Unfriendly Bad Mad Mean Smelly Hot Late Overbooked Understaffed Expensive Cramped Narcs If they were a fruit they’d be rotten durian

At the beginning of the flight there was some turbulence and the announcement was made that there would be no beverage service. The turbulence only last about 5 minutes then it was smooth sailing. I noticed that first class got their service, but the rest of us did not.

Update departure times in a more timely manner. We are not boarding on time if the plane isn’t arriving until after our scheduled departure time.

Update.us on flight information in a more timely manner. Don’t say we are boarding on time ten minutes before the boarding time when the aircraft isn’t arriving for another forty minutes.

Took off on time and successfully avoided weather that looked to be a problem along the way

I liked everything. Except that my neck was hurting on the seat. I couldn't sleep.

We were delayed Al ost / hours after boarding so that maintenance had to add oil to the engines. Then the oil they grabbed had been left out in the Dallas record cold and was frozen. They had to go back to the hanger and grab some that was not frozen.

They changed my seat from one that I had paid for as an upgrade to a regular seat at the last minute.

Flight was empty so had a whole row to myself. Still had to wait to get the bag due to the negligence at Palm Springs departure.
