nothing for delays and refuse service.when asked for the second flight. the first is good though

The front desk attendant was rude to everyone in an absolutely careless way.

Wonderful as always! Pleasant staff, smooth ride, and timely departure.

We left late; had to land in Minneapolis unscheduled to refuel and then landed in interior instead of lax at 2am......

Flight was scheduled to leave at 6a and delayed for 5 hours due to “mechanical” issues. Everyone else on the flight received an email voucher for $24 of food for the delay, except for our group. Also the carry on luggage bins were full and the crew requested that everyone to pass their carry ons back up to the front while everyone was still standing. They gave no other direction and kept rushing the process. After all bags were sent up, they then asked for seat #s to go with each bag… They should have probably had everyone get to their sits and then pass the bags up in a controlled process.

From Las Vegas to Boise all went well. However, our flight was delayed in Boise and I missed my connecting flight from Seattle to Pasco. Moreover, the last flight to Pasco was full and I was booked on the 11:30 flight Sunday and given a hotel accommodation. However, I was scheduled to deliver the Sunday morning service at my church and needed to arrive no later than 10:00. Therefore, I booked a Delta flight scheduled to arrive in Pasco at 23:09. My piece of luggage checked in Las Vegas arrived in Pasco earlier today. I waited at the airport for over an hour last night to speak with an Alaska agent to no avail. I went back after church this morning in search of my piece of luggage and it could not be located. After waiting for 40 minutes to speak to the agent authorized to take my claim, he announced that he was closing the counter to assist on the flight line but not before providing me with a telephone number that would help me with filing my claim. Before I was able to make the call (due to other factors) I received a call from Alaska agent informing me that my luggage had just arrived and I am now waiting for it to be delivered. I deliberately took the more complicated route home to ensure that I would be home in plenty of time to prepare for myself for the Sunday service and accommodate my relatives’ needs. I believe the airport is undermanned given the number of flights coming in and going out. It was fiasco last night with three flights waiting for luggage and another flight landing within minutes. Today’s problems stemmed from a lack of cross training and a serious amount of cargo/baggage going out and too few people scheduled to cover.

I understand it’s their right, but when two of my party missed the flight after checking in it seemed insensitive to cancel all of their subsequent flights and for us to lose the extra seating despite having paid for it @ the very least we could’ve been refunded for the checked bags that we prepaid for and never used.

The seats were not very comfortable and there were no TV screens. Boarding was pretty fast because there were so few people on such a small plane and I appreciated that they still gave us our snack and drinks, however I really wish they would come up with a good gluten-free snack.

Every thing is on time, boarding, landing nice and smooth. But No tv? No food for 6 hours flight?

Flight crew and flight were good. But it departed two hours late.

This was the worse experience. They delayed our flight twice and we still had to find another flight to get home sooner which was alos delayed. Also, the flight attendant named Ginny on DL9890 leaving at 4:13pm on 3/23/26 was extremely rude.

I love Delta the flight attendants were personable and the flight arrived 1/2 earlier thanks expected. All a plus. The gate agent was a bit flustered but even with that I still had a good experience. Her supervisor assisted me.

I am still at the Airport! Delayed Delayed and Delyaed

The first class flight attendant was awful to everyone. Very rude; no customer service. She should not be working in first class.

Love delta smaller commuter plane so no entertainment and paid wifi on MKE-LGA leg was extremely unreliable and slow

Delayed. Hot. Passenger next to me was so large I couldn’t move.

The flight went very well, but the flight attendants didn't serve and food or drinks other than 1st class due to rough air but to be honest it wasn't that bumpy and I felt that they could've at least offered water and coffee perhaps. Also serving 1st class only is a bad look. I've been in 1st class many times and I would've felt that if the turbulence was too rough for the main cabin, it would be too rough for 1st class too.

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

My seatback screen didn’t work so that sucked because that’s what I was going to do on the plane.

The whole experience was excellent. As it most often is with Delta

They promise free wi-fi prior to boarding and then once on board you are informed you have to purchase wifi even after being a mileagePlus member.

Both our flights were delayed. Almost didn’t get in the second flight. Staff was rude to the bone.

Everything went well except the turbulence what no one have a control of but pilot and crew handled very good!

Much better than Spirit. I was please by the easy fast check in and boarding

The attendant on board was amazing. She should be doing business/first international long haul.

Perfect flight. Smooth flight. Arrived 20 minutes early at destination. Excellent service.

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

Flight was timely, relatively comfortable, with decent entertainment and food served. Only problem encountered was with the free messaging which I highly appreciate, but it did not work from iphone to non-iphones.

This flight was perfect. No complaints and only the highest regard for the crew and ground staff and how they executed perfectly. I fly a lot with United and would request predictability and transparency in their operations instead of last minute changes.

My flight from LGA was cancelled and my rebooked flight from JFK was delayed numerous times. I will now be getting home after 2am.

Flight was delayed half hour before boarding, but when I checked flight aware the plane that would Pick us up had a delay of more than an hour. AA should let us know in advance to avoid waiting several hours in the airport

There was no inflight service. Once we landed we were delayed to find a gate for an hour and a half which was 1/2 the total time in the air.

The gate agent had a really bad attitude and refused to help me get on the standby list. She just handed me a card and said I needed to call a number. I asked her to help with the AA app on my phone and she just shrugged and said she didnt know. After a few phone calls, I eventually just went to a different gate agent on the other side of the terminal and got the help I needed.

One day, I do so hope for a gluten free snack! Seems like with the rest of the world FINALLY figuring out what gluten free is, American Airlines would too. Fingers crossed!!

the plane was so hot!! the air-conditioning was barely blowing. The flight was delayed, and we had to sit on the hot plane before take off for an extended amount of time, waiting on international passengers. Would not have been so bad if it was not so hot. They said it would get better after take off, but it did not.

I am very appreciative of the help provided to me by Dennis and Whitney. I had lost my phone at EWR airport and they were very kind in assisting me. This included advice on how to file a report and also helping me connect with family. The pilot was also great about keeping passengers updated on the flight progress with regular communications over the system.

I would like the crew to talk LESS over the PA and specifically about credit card offers. I am trying to work, sleep, watch a movie and the PA was booming about a credit card offer. Could we go back to the days when the customer was more important than selling a credit card?

My seat tv didn’t work the whole trip. And the seat space is too small despite being seated at the front.

On the plus side, crew was attentive, drinks were cold, and in-flight entertainment selection was better than some other airlines. On the negative aide, Plane was delayed almost an hour, either no announcements from the gate crew. Biscoff cookies are gross, appreciate airlines that give a choice. Also, crew had no personality or enthusiasm at all.
