3 hours late and all they have is was a $12 meal voucher. That’s not even enough to cover fast food.

3 hours late and all they have is was a $12 meal voucher. That’s not even enough to cover fast food.

Among the poorest flights I’ve had with Delta in a while. Entertainment system failed completely on a 7.5 hr flight. Crew seemed distracted and not the normal friendly crew. Flight overbooked it seemed… very crowded.

If I can, I always fly Delta. I’ve found their service to always be reliable and pleasant.

You could have not cancelled the flight (AA, which I will be flying from now on) left for BOS despite the fictitious weather issues (that no one in my Boston family could see). You could have rebooked my direct flight to another direct flight instead of sending me though JFK, the worst US airport after O’Hara You could have rebooked me on a Main Cabin seat (like the one I paid for in my original ticket instead of putting me a the last row on JFK->BOS leg, pocketing the difference in ticket price But I do not really care whether you will ever do that in a future because in a future neither I nor anyone from my company (unless they pay out of pocket) nor an of my clients and partners (if they heed my advice) will ever be caught dead on any of Delta flights

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

It is a modern tragedy that any airline expects you to travel for 14 hours in such discomfort and that the only way to add comfort is exorbitant prices. I was in pain by the time we landed. Shameful.

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

I had a great flight. Everything went smoothly and the flight arrived early.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

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.

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

The flight was delayed instead of leaving at 11 it left at 12.20

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Good movies, iffy pay WiFi, food ok- on time though and that was great!

Awful…flight was delayed more than 12hrs, missed all connections to Fort Wayne, IN, had to get flight to another city 2 hours from my destination, flight was again delayed by 40 mins because they did not have enough fuel, again missed a connection, finally arrived in Indiana at 11pm…but before my 2 hour drive home, ay, no Five That Our Luggage Never Made On The plane and Still In Chicago
