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

The main person that was coordinating everything was a short white/light skin Spanish man and he was very rude. It honestly made me feel like it was everyone’s First day at work. His announcements were very not reasonable and they did not make sense. The stewardess on the flight that made the announcements she didn’t even know what she was talking about she sounded inebriated. There were no snacks or drinks on our flight there wasn’t even much turbulence. This flight was not enjoyable nor was it what a Delta flight should be and just this past week I flew with Delta 3 times.

nothing Delta could do... the person sitting next to me was huge and overflowing into my seat

Crew was great! I need wheelchair assistance and they knew who I was and updated me that my chair was on its way and to just hang tight. There was some turbulence but the captain announced we would be going thru it and he handled the plane well. Landing was soft and his.

Aircraft very cramped. Check-in was great with an agent helping us. Food was almost non-existent. Pre-flight went well once I got the app reloaded on my phone since we don’t fly much anymore.

I like that it got us where we were going. Everything else needed work. It was 1/2 hour late and we took off an hour late. The plane had to be cleaned and the disabled loaded on board before we could take off which took forever and then we sat at the terminal FOREVER before we took off. The ride was so bumpy that they couldn’t serve drinks and snack but to about 1/2 the plane. Seriously we should have flown out of Fort Lauderdale. We probably would’ve gotten home several hours earlier.

Flight was on time, the staff was personable & professional, & the plane arrived on time.

Flight was great. DELTA did a fantastic job! FLL airport was chaotic!

You lost my luggage!!! How frustrating!!! Now they can’t find one of our bags!!!! I really don’t have time for this!!!

Fast boarding and exit. Different snacks other than almonds and sun chips.

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

Boarding was friendly and quick. While the plane model was older with no live tv, the entertainment was full of movies and tv shows. All food was available. Pilots were very communicative with status of the flight. Flight landed on time.

The Palm Springs to Chicago O’Hare was on Time and Palm Springs airport is easier navigate. As our connection was only an approximately 50 minutes, we asked staff for insights for the Chicago airport in terms of transferring into the other terminal from which our flight left, and they were unhelpful. However, the United App was very helpful in terms of notifications and even providing directions. The Chicago to Detroit flight was significantly delayed which we all know does happen. However, there were very few updates or notifications as to why this was happening when we would actually arrive. It took nearly 30 minutes for bags to make it to baggage claim. We arrived nearly 1 hour late on a 40 minute flight.

Flight cancelled due to fog. No other flights available for 36 hours. Directed by United to book passage on another carrier, and submit receipts for reimbursement. Did that. United now states they will not reimburse. Currently out 2 grand.

The flight was delayed by 4 hours !!!!! It was very uncomfortable , and they told us only one our before departure

The flights from Ottawa to Albuquerque went smoothly enough though on on flight they didn't have how water for coffee or tea and on another there there was no ice. The return flights from Albuquerque were delayed by mechanical problems on both flights. Ottawa was a ground crew maintenance issue.

Entertainment was okay not because anything was wrong but it is a short flight so having no wifi is annoying but understandable. Crew was outstanding as usual

Those seats were way too narrow. I had the middle seat, one person was a very skinny person and we still couldn’t avoid touching each other anytime one of us moved. The other person was larger and we were basically sitting in each others lap the entire flight. There was zero entertainment. The flight was long enough to justify tvs, but no. Gotta sit there in your infant seat and twiddle your thumbs.

Flight was fine. It took an unusually long time to have baggage delivered to the carousel in ORD.

Average - flew with Jet Blue internal and it was far more comfortable and better food and entertainment. Notable difference

The flight got canceled due to mechanical issues, and he to be rebooked and missed my appointments for that day

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

The only problem experienced was a ground stop in Chicago due to weather. But the crew handled everything professionally. They prioritized rebooking those passengers who had connecting flights and then deplaning the other passengers. When the hold was lifted, they efficiently re-boarded all the passengers so that we could depart before our departure limit expired.

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Turn on the heat. Flight was way too cold from Arizona to Chicago.

Perfect flight. On time departure and early arrival. Smooth flight.
