This time it is good, no delay and right on time

Miss bigger screens for movies Staff was friendly Seats comfortable Bathroom line long

If there were movies it would have made the flight much easier.

Plane was delayed getting boarded and then again delayed in take-off order. Alaska Airlines must have very little clout at JFK so they don't get priority treatment. All the delays meant we missed the last flight from Portland to Eugene. Alaska did give us hotel voucher for the night...but sent us to a downtown Portland hotel rather than to a nearby airport motel which made for a longer ride at night and then again in the morning. Just made an already long, late night even longer. Hotel was an old outdated Hilton in a slightly seedy part of town. Alaska gave us Lyft vouchers for getting to the hotel, but the return voucher for getting back to the airport in the morning didn't work.

Could not check in online - had to get boarding passes at the ticket counter and our daughter got bumped off our connecting flight. NOT OK!

I purchased the internet during the flight and it stopped working after 1 hour, so I barely got to use it.

I had a negative experience, the flight delay was very long, I didn't like it

The seats in first class are very dated and quite uncomfortable. I don’t need lie-flat seats for a 6 hour flight, but more recline is really necessary.

It was great. There was legroom. The food I ordered was creative and flavorful. The crew was kind and fun. Definitely would fly with them again.

We were in first class. Food was surprisingly good. Boarding was easy. Seats were lumpy. No video screen ...really? Service was good. Phone support was good

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

I believe that a four-hour trip should have a meal. Delta had none.

Was charged for my luggage despite having been on one ticket from an international flight. Too tired to argue after 15 hours on flight. Was charged for rechecking it at JFK airport. Not sure why those off Kenya Airways were required to do that.

Flight was canceled, and no effort was made to help with rebooking, no hotel vouchers, no car transportation and minimal food voucher and most places for food were closed by the time the voucher was given. Waited for 3 hours for bags. Simply the worst travel experience I have ever had

At first, we were on the runway for about an hour, literally. The Captain did explain that the Control Tower just had a change shift (sounds like an unrealistic excuse) and then that we had to change a runway. A regular economy seat is made for 12 yo twiggy. I understand Delta wants to push for an upgrade, but after sitting in a Comfort seat and in First class. I would say First class is not worthy of my money. The landing was delayed because of the weather in NYC, I don't hold that against Delta, of course. The Captain did alert us to that upon takeoff in Vegas and again as we reached NY.

Not a "Delta" issue, but a JFK issue: We booked a connecting flight with 3 1/2 hours between to clearn immigration and customs. Our inbound flight (BCN to JFK) was on the taxiway 45 minutes which ate into our layover time. Immigtration was insanely quick with the CBP MPC app; however, clearing TSA (again, after we were ALREADY cleared in Spain on the inbound international flight) took over 95 minutes. This left us with 10 minutes before boarding the connecting flight (JFK to SAN) to walk to the far end of Terminal 4 and try to find food. We didn't find any food that could promise to serve us in under 10 minutes so we boarded the Delta flight after coming off a plance and an 8-hour flight knowing that we wouldn't be served any food on the next 5 1/2 hour flight. I feel like Delta needs to put pressure on the JFK TSA to open more screening stations (by our count, we saw only 5 scanners open and a line of - as we said - over 90 minutes. The insult is that we WERE ALREADY SCREENED through TSA, but as you come off one flight into the USA, you have to go through the whole process again. It seems like if you have a connecting flight, there should be a way to pass through immigration and customs without needing to return through TSA.

Overall, aside from the baggage issue, it was as good as one expects.

The entertainment and wifi mostly didn't work on this flight.

Terrible entertainment system - kept freezing and audio kept cutting out. Snacks were mediocre at best for a 5 hour flight.

I am still upset that my bag was lost on a recent trip to Rome ; we were inconvenienced and out €150 Euros ; delta has refused to reimburse us

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

We arrived 4 hours early and still almost missed the flight because they weren’t able to access one of the boarding tickets. They then sent hour bags late and we were all of our without clothing and eventually had to take an expensive cab back and forth to the airport as they wouldn’t deliver the bag which arrived late at night that day and we would have to wait until noon the began day (messing up a second day of plans). Also, all the food has dairy or pork. No vegan or even vegetarian option in the flight—even for purchase.

The comfort of the seats was great, the crew eased my child’s anxieties and the fact that I had full cans of my beverage choice was great.

Pathetic check in experience at JFK. Everything is self check in. Not enough staff present to help with when the check in process or the kiosk gets stuck. Staff present not welcoming or pleasant at all. On the other hand the NY based flight crew was great. Courteous and friendly throughout the flight. Special meals leave a lot to be desired. Kids meals should be made available when kids are flying and same goes for special kids meals too.

Waited on the runway for takeoff for 2.5 hours. Air traffic rerouted us. The plane didn't have enough fuel, so had to go back to the gate. Had to wait for a new pilot. Should have landed at 5:22. Didn't land until 9:10. Trash flight.

There were five broken seats on the plane. The crew was very rude in telling people they had to get off the plane and get a flight the next day. No call for volunteers, but telling people they had to get off. One woman was flying with her elderly mother and daughter and was told she had to leave or all three had to leave. Fortunately, a volunteer offered to stay. The situation was handled poorly.

Delays on all NY flights. There was no communication on why but they didn’t say it was weather. Other carriers were not delayed.

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

They cancelled our flight without warning OR a refund. Never doing business with American Airlines again! This is the second AA booked trip in a row that we've had challenges with.

I got bumped due to weight restrictions even tho there were empty seats on my flight. I got put on an other flight with a stopover. My flight that originally was going to take 5-6 hours ever up being 14+ hours and my luggage arrived to my destination without me because I was made to check in my luggage on my original flight when I was deemed ok to board only to be asked to deplane. Worst flight experience.
