I noticed that the planes seem to be outdated. There was no entertainment per se. Also, the waiting area did not have any working electrical outlets

Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

The food is terrible. The staff is wonderful. Comfort is good.

Left on time, a bit delayed due to headwinds most of the trip.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

My flight was delayed about three hours. I got home at 3:30 in the morning very bad experience.

I had a positive experience on American. I'm blind and traveling with a guide dog and the flight attendants were so kind, friendly, and helpful towards us. They checked in on us during the flight and they made us feel comfortable and welcomed. There was an hour delay before depature, but overall the flight was a smooth ride. I appreciate that there were no issues on this long flight back home.

Did not get any refreshments. Crew was very nice but limited. Small seats

Terrible. Our luggage was delayed and couldn’t be delivered for several days. We got bad information from the airline agents at baggage claim. We had to pick up our car so we wouldn’t be charged for an extra day. We got lost in the maze of airport parking. The baggage claim agents didn’t offer us any compensation for our extra time and expense. We are tired, hungry and very frustrated.

The flight was flawless and we even arrived between 20 and 25 minutes early!

Typically flights with AA are good. The staff are pleasant, welcoming, and efficient.

Mostly good. Flight was crowded but Airline personnel were very friendly & accommodating. It would be good to have savory snacks rather than just sweet Biscoff cookies.

We had 3 flights. 1 & 2 were on the same plane but we had to de-board just to re-board 30 mins later. That may have been due to a crew change though. Our 3rd flight had a couple “maintenance” issues that held us up. They were quickly resolved but it took forever for someone to bring the paperwork needed so we could leave. Apparently there was a computer glitch so a driver had to bring a physical copy. It delayed us about 1 1/2 hrs. The flights themselves were smooth & no problems. For boarding, I don’t know why they don’t start with the back of the plane & move forward. It would eliminate the back up from people trying to find their seats & put their bags in the overhead bins. Unless you’re on an overseas flight, there is no food, you get a beverage & either a small bag of pretzels or a biscuit cookie. Take your own food or snacks of you want something more.

The actual trip was fine, however, the changes made to our flights and the layovers were had to endure were awful.

Most things were ok but the main problem was the cabin staff; they were very abrupt and not very friendly. They were busy and often rushed, snatching drinks off people before finished and bossing them about.
