Idaho Falls is not a large airport, so it was easy to find my way around. Take a meal if you want more than a snack.

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

This flight was a first class choice and left much to be desired. Seat backs on seats were falling apart and torn. Seats actually didn't come to a "full & upright position". Pull out table was sprung. Not any significant leg room. All in all we were on an obviously older plane and felt overcharged for what we received as first class.

A 12 hour flight during the day with one real meal service - are you kidding? Also the breakfast was one of the worst and not what was listed

Flight was delayed several times. At one point, they "pulled back" 15 minutes from the delayed boarding and sent a text saying we would board sooner than previously advised. The flight then was delayed again. And when we boarded, there was an unspecified technical issue which had us waiting in the plane for about an hour.

Delta is a good airline. I've never had an issue with Delta. I'll continue to fly with them until they show me that I shouldn't.

The only thing nice I can say is the flight crew was really nice and apologetic about the situation. They shared as much information as they had and advised us on what we could do about missing connecting flights. The boarding process was so slow. The gate agent was working by herself and should have had someone working with her. It took almost an hour to board because she was trying to board a full flight of people and provide customer service to everyone who was flying standby and/or had questions. It was really chaotic. This didn't help the fact that we were delayed and folks were missing connections the longer it took.

The gate attendants and the crew were terrible. Because of high winds, they needed to carry more fuel, so they had to get volunteers to take the next flight at 6 am the next day. They did a terrible job of it - our flight ended up taking off just under 3 hours of the scheduled time. I hope to never fly Delta again.

Did not realize internet screen was hidden between seats and no info printed!!!!

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Very good flight crew and very nice people staff were incredible especially the gate agent
