My only complaint was how far it was from plane to baggage claim

My only complaint was how far it was from plane to baggage claim

Cancelled the flight cuz they sent the WRONG plane and then they promised to rebook us and let us know within the hour what our next flight was. I have heard nothing after 12 hours and can’t get ahold of anyone.

nothing for delays and refuse service.when asked for the second flight. the first is good though

Not bad. Due to not buying a seat, on the way back, my seat was not assigned till 2 hrs before the flight left. Got me worried I wouldn’t have a seat.

It was not a good experience, the flight was delayed 3 hours, the gate staff were super pushy to get bags checked claiming it was a full flight, there were about a dozen open seats from what I could tell. The intercom from the pilot seemed to be broken, it sounded like the pilot was speaking with a mouth full of marbles.

There was an issue with the plane and it was late getting in. This caused me to miss my connecting flight from PDX to BOI. I had to ask if they would provide me with a food voucher and they did but didn’t seem to concerned about my delay.

The flight was delayed by 2 hours for “routine maintenance”and because of that I arrived much later iso my Uber ride home was $100 when it’s normally $50.

More or less, this seemed like a mismanaged group of great people who would crush at this job, if only they were given the resources to do so.

Plane destination at the Gates were mixed up at Spokane airport. Text from website didn't match rithet

It was fine. I upgraded to premium economy & lived the extra legroom. Unfortunately, I was seated next to a man who sniffled A LOT during the flight and had his earphones on so loud that I could hear the music sitting next to him!

First class is comfortable. Enjoyed a movie and was able to relax compared to coach.

Loved flying First Class. Very comfortable. The seat was amazing. Enjoyed a movie and was able to relax so much better than in coach.

We landed and sat on the tarmac for 45 minutes because they only have one gate at the airport and there was another plane running late so we had to wait

The WiFi was not working. That made for a long flight.

Absolutely no communication on why there's a delay and multiple flight time reschedules. I would have canceled the flight and drove back home if I known it was going to be rescheduled 3 or 4 times.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

I was in first class and literally the men behind me were so aggressively loud I moved myself to economy. This has become so common on Delta - people using audio without headphones, and men on 12am / late night flights drinking and yelling to talk to each other which prevents anyone around them from resting. Pretty crazy to have to move from first to economy (poorer service, less comfort...). Wild wild. Looking into other airlines.

Love delta smaller commuter plane so no entertainment and paid wifi on MKE-LGA leg was extremely unreliable and slow

Stop changing gates. Stop cancelling flights Stop moving my seat.

Extremely disappointed with Delta. They canceled flight last minute and then I rebooked the other flights and with which were delayed as well
