On my way home I had a layover. The flight from ATL to CLT was amended 5x while I was waiting. I could have driven home sooner. Overall from Dallas, Tx to Charlotte, NC I started my trip at 4:30pm, I didn’t get home until past midnight. I know things happen, but 5x to make me run back and forth in an airport from different terminals is excessive. I also upgraded to comfort + , I didn’t feel it was worth it. There was no benefit

They did a fine job. Can't wait to use Delta in the future.

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

Seat back monitors and outlets were dead and not working.

Everything was great except for the seat. The backrest would not stay in the upright position.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

Flight delayed about 2 hrs so it made it a VERY late night

It was a crowded flight. They did the best they could.

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

they made me check my carryon. There was space in the overhead bins.

Nice flight, nice crew but no cookie or napkin with my seltzer.
