Horrible. This was not first class. This was a connecting flight whi h was late. My original flight never came. I hated the fact that delta gave me a connecting flight from New York to Orlando Florida. No meals and the television screens were not working. There wasn't even any power to charge your phones. This is NOT FIRST CLASS DELTA!!! Do better next time!

I hated the fact that delta gave me a connecting flight from New York to Orlando Florida. No meals and the television screens were not working. There wasn't even any power to charge your phones.

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

Seat back monitors and outlets were dead and not working.

The experience was good and the flight departed on time and landed early

The flight was delayed but we got to our final destination.

Boarding was great. The flight landed early. It took the crew over an hour and a half to bring out drinks. I paid to upgrade my seat to Comfort+ only to be near a crying/screaming baby who was seldom quiet. Noise-cancelling earbuds didn’t even help. Waste of money to upgrade.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

This flight was supposed to land at 10:55 pm on January 14th. Instead, it landed at 3:20 am on Monday, January 15th, resulting in a completely lost day due to not going to bed until 5:00 am.

Boarding super slow with people allowed to linger in aisles

There were choices for the snacks. Good choices and tasty lunch and breakfast as well.

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

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

Too many fees (but that seems to apply to all airlines nowadays)

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Everything was very good. Boarding and takeoff were on time and organized. Had a good flight

Wheelchair assistance was not complete. The person left me at the departure gate without informing the groundstaff of my requirements. I had to walk to the departure counter to ask for help to reach the plane door. The crew informed me that in future they were not allowed to help passengers like me, senior citizen and Wheelchair passenger with placing their carry on bags in the overhead compartments!

Flight was delayed by over an hour and gate checked bags took 15 minutes to be delivered to the jet bridge.

Seats are way too snug for my hip to knee ratio and the recline on the seat in front of me made my experience worst. My legs had no room at all. Not a plane for people 6 ft or over unless you fly first class.

Delayed for maintenance issue?? Should have been addressed before boarding. Put my bag on an earlier flight, but didn’t ask if I wanted to change to an earlier flight. Arrived to find my bag locked up and no agent to be found when I landed.

We learned certain countries (a few) require a notarized letter from an ex to give permission for children to travel to those countries with the other spouse together with birth certificates. To find this out one hour before flying—not good. Nowhere is it documented by the airlines though they require it. Make sure about all documentation required.

It was a good flight. Of course it was full, but it went well.

We sat on the plane for 1 hour because the airline was short handed could not be unloading.

We are gluten free, there were not any available complimentary gluten free options.

Flight delayed 3 times. We were directed to go to a gate across from our gate. The plane wasn't there yet so we had to wait for it to arrive, then deplane everyone and then wait again for the plane to be cleaned. After 45 minuites we were allowed on the plane. The first plane had mechanical issues. The 2nd plane must have had bathroom issues because we did not have any food service whatsoever. No snack or beverage. That made for a long time not to have anything considering that we had just made it to the original gate and we had no time to stop to get food or a drink. Then we didn't want to leave the gate to get food because we wouldn't know how much longer the delay would be. Then the next gate change. Had we been told that the total time would have been aprox 45 min later we would have left to get food and a beverage. We had to wait again for the okay to the pilot to take off so we were on the runway for another 20 min. Overall, we were delayed over 2 hours which felt like 4 hours.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

Me and my husband experienced very bad in American Airlines. We missed our flight going to Doha. The American Airlines was delayed we arrived already 10:27pm. Supposed to be 9:40 pm. So what they did they rebooked our flight and they gave us a hotel. When we arrived at the hotel the front desk said it was fully booked already. Oh my gosh! I said why did you accept the booking if it's fully booked. The guy said that's American Airlines they just book even it's already full. That's 2am already, we have nothing to do so, we decided to go another hotel. We pay the room, food and taxi. Pls give an action on this matter. Refund our expenses and give us more compensation. Not only our room, food, taxi but also our efforts, tiredness looking for a room that can accommodate us.

Horrible. Flight was delayed and very bumpy. I was super unhappy

No meal on a cross country flight? SFO-MiA is pretty much the definition of a coast to coast flight. No meal provided. Sky high wi-fi rates too. Stop nickel and diming your customers.

Absolutely filthy flight and not equipped for a trans US

Overall okay. Ipgrades ate worthless anymore. Wish I’d not been so loyal To them for so many years. Platinum many years. Gold for life. Usually 20th-30th on upgrade list.
