We were delayed. We spent more time waiting on the plane than actually flying (it’s only a 37 minute flight). Other than that, it was fine.

We were delayed. We spent more time waiting on the plane than actually flying (it’s only a 37 minute flight). Other than that, it was fine.

Only offered water, no snacks provided, and it was cold on the plane, everyone was wearing sweatshirt or jacket in June. I asked for blanket, but crew said they didnt have anything and would turn the heat up, that didn't happen, so for 6 hours I remained cold.

Flight from New Orleans to Seattle to Anchorage was delayed for 3 hours My flight from Seattle to Anchorage was not rescheduled. I had to call the airlines to tell them to get a flight from Seattle to Anchorage they finally got me a flight If I hadn’t been aware of this problem I don’t know how long I would of waited in Seattle to get a flight to Anchorage!!!!!! Return trip from Anchorage to New Orleans in Seattle to New Orleans I was at the right gate when I realized something was wrong they had changed the gate without notifying the change l finally made it on time with minutes to spare & exhausted

I was at risk of not getting on the flight, as when I presented my boarding pass at the gate, it showed me as not having checked in. I was sent to the desk as the last of the other passengers boarded. The agent there said he could see that I had done all of my part and allowed times recommended, but it showed me as not checked in and he couldn't figure out how to correct it. He actually asked them to hold the flight as he struggled with it. He called for support, someone corrected it, and he printed boarding passes for both flights to reduce further issues. I did get on, and needed to ask someone to exit my seat.

Eddie, our flight attendant in the back was excellent. He was very kind and concerned for our happiness and comfort before and during our flight. He made the experience great. We had to deplane due to a ground delay and he made sure we had snacks and water to keep us comfortable while we waited. Overall, it was a great experience!

I liked the food. The WiFi was out and the flight was late.

Flight was delayed which caused us to have to change our connecting flight. Grilled cheese sandwich was served very hot.

I was so cold. I am so glad I brought a short sleeve shirt and a long sleeve shirt and a jacket. Also knee high socks and slippers

We were late so that was what was worst part

The Alaska app and website were not fully operational. I had to spend about 15 minutes at the counter doing things that should have been completed online. The agent was very nice and helpful, however.

Crew was excellent. Comfort seats not as nice as other kinds of planes.

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.

It was a great flight and the stewards and stewardess were all kind and accommodating!! The seats were comfortable and entertainment screen excellent!

There are 4 flights in consecutive gates with about the same departure time. Two flights were boarding at the same time. One was delayed or boarding would be happening at the same time. I am not sure what Delta and LAX need to do to have a better layout at the end of Terminal 2

Flight was an hour late, who knows why. It was OK, nothing outstanding.

Only not having an assigned seat was an issue. Rest was great

There was a security issue at the airport and we were unable to land. We circled endlessly and then landed at another airfield for fuel. We then circled the airport again, almost landed but didn’t fully touch down before circling again. I am thankful to the crew for keeping us safe- the issue was the airline and staff at the airport getting us seats on our connecting flights. That part was hours of searching for someone and getting in double my steps.

Boarding was organised and relaxed. Crew were fantastic! Seats were lacking padding causing butt pain and stiffness.

I like for how they process during check in. It was very smoothly.

The flight was scheduled for 2:30 PM. Early in the morning we got a text message saying the flight was delayed and rescheduled for 3:00 PM. We got to the airport with that in mind. Then we got a message during check-in at the flight was rescheduled again for 2:30 PM. We almost missed our flight. In fact, our bags Were told that they would not make it. At the end, everything worked out. But it is very stressful.
