It was as good as it could be. Flying is not a pleasant experience these days.

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

Flight delay was frustrating, also you cannot checkin online without delta app, web browser check-in throw errors

Got on the plane and sat there for an hour before departure.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

Cramped seating for me. Luckily it wasn’t a long flight

5 hour delay. They blamed the weather but it was the computer issues they had been dealing with for days.

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

The captain was amazing and kept us informed throughout that there would be some rough air. The flight also got delayed but we were able to actually leave on time, which was great.

The staff did not do a good job of getting everyone boarded quickly, so we missed our take off window and had to sit on the tarmac for 20+ min waiting for our turn. The plan was old. Pockets on the back of seats were torn and tearing off. One of the attendants was rude-she would ask a question but he walking away before you finished answering so she kept getting our drink orders wrong.

Gluten free snack options and meals that offer both gluten free and dairy free.

Not a bad flight but a long delay boarding and taking off due to the pilot not arriving on time.

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.

I almost missed my connection in Chicago due to having to wait on a gate to be open I am assuming. Having to run from E terminal to C terminal and I barely made it there before they closed the door. This may not be the actual airline's fault it's crazy how there is so little time between flight especially when they are placed so far apart in the airport.

The Wi-Fi did not work, so you weren't able to watch entertainment on your own device. They did not have wired headphones so you couldn't watch it on the in-seat entertainment screen either. There was plenty of time to do a drink and snag service but the flight attendants chose not to.

Great experience, boarding was fast and efficient, so much so that we arrived to Chicago very early

This flight is a quick way to get to Chicago, but a bit expensive.

I liked that the flight was nonstop from ORD to CIU for $200 round trip.

Some sort of compensation for missing work because of a cancelled flight that was United’s fault

I was told we'd have a hot breakfast option in first class, so I chose not get a hot breakfast. It was a very strange meal, but the fresh fruit was very good quality. Service was excellent from ORD to ELP. No service from MBS to ORD, not even water. However, when flying American from FNT to ORD, which is a shorter flight, they at least pass out snacks and offer water.
