The WiFi has been awful on my last few Delta Air Lines flights.

The WiFi has been awful on my last few Delta Air Lines flights.

Only one side of the heafphone jack work. Crew was friendly and helpful.

It was reported to the passengers that Delta failed to schedule the crew properly. This error caused the pilot to show up about 30 minutes late. All in all Delta's inability to take care of this basic function resulted in about an hour delay.

Don't need the male flight attended lecturing. The whole plane on how to act when there was no problems.Other than that everything was great

Loyal Delta traveler, but last nights flight was a train wreck. Seated in 1B after multiple delays. Then we couldn’t takeoff because of an issue with the passenger that was ‘not in compliance’ and had to deplane along with the threat if they did not deplane, all the passengers would be required to do so. Finally they were escorted off, but the experience threw off the crew. Disruptive for everyone. Service was a mess, televisions didn’t work, bathroom door kept swinging open during the entire flight whenever empty …

Like all flights, the seats are small and not comfortable. My first leg was delayed but delta rebooked 2nd leg so my arrival at final destination was only 2 hours later than original flight.

Older plane and it came with Fleas and flea bites!

All good on Delta's part. Passengers could be a little more courteous to each other.

The fight was about 2 1/2 hours delayed, but that was weather related. The flight was also overbooked. But we were in Comfort plus so the flight was fine for us.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

The food for long haul was poor compared to Singapore airlines economy. Pasta plain with tomato sauce . Singapore airlines give me Hagen dash small ice cream cup it was great. The choices of dinner course Singapore air also much better The crew mostly friendly. The economy seat are as expected.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

There was no air on the plane and it was very hot.

Flight crew was amazing! I don't like that the Polaris seats are side-by-side.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

Flight was 3 1/2 hour delayed with no credit or meal vouchers

Smoothly flight, pleasant flight attendants. I wish there were better food choices.

Everything was awful Flight attendant was condescending, rude and not helpful at all. Small outdated plane. No service, uncomfortable seats. Flight attendant was really the worst. He used hand gestures to communicate instead of words and whenever he used words he was condescending.

They need to improve their boarding process. Group 1 and/or paying first class passengers shouldn't be in the middle of boarding process

late departure due to some unspecified issue with ventilating the cabin. They got it running but it was FREEZING for the whole flight. I asked for a blanket but they didn't provide one. They could not turn up the heat. it was quite miserable.

The boarding process was incredibly slow, as was deplaning. They started beverage service and there was an extremely small amount of turbulence, so they discontinued it. They said they’d resume if possible, but even thought the rest of the flight was perfectly smooth, they didn’t bother. Getting our checked bags took longer than I’ve ever waited and they couldn’t even tell us which carousel they were coming out on, so everyone was running back and forth for 30 minutes.

It was really good. The boarding was good and smooth. They even checked our carry ons if you wanted to without any charge.

Boston ticket agent Cheryl Porter is WONDERFUL. Our Iberia flight to Barcelona was cancelled the morning we were scheduled to leave and Cheryl was our super hero - she found us seats on a flight to London and on to Barcelona. Truly a “can-do” attitude which we appreciated so much after the Iberia ticket agents told us there was “absolutely nothing they could do”. (As did the customer service agents at Iberia’s call center) Ms Porter is truly a wonderful person who genuinely cares about travelers!

Flight was delayed , waited in the tarmac for 3 hours and then came back and was cancelled

Extreme weather delays. Missed my flight to France and I ended up leaving the plane.

I arrived to LaGuardia Airport 50 minutes prior to my 6am flight but was told that I was too late and would have to flight standby to Dallas in order reach my final destination of Jackson, MS. Hundreds of people were in my situation but the agents chalked this up to being normal for any day. Had my been able to board my original flight I would have arrived at my destination by 10:30am. I didn’t arrive until 7:30pm which included a 30 minute wait on the tarmac. Strangely my luggage arrived at my final destination at 12:30pm of the same travel day. This was by far the worst travel experience I’ve ever had.

I was not given the option to get on a different flight even though I was going to miss my connection due to weather delays (I did). When I called early in the morning, they said it wasn't delayed long enough; though I knew it would be by the time it was time for the flight ... it was and by that time it was too late. I wasn't given the option to pre-board with my toddler, and the food service was less than normal due to delays .... at least that's what the crew said.

They were not helpful in letting my baby and I rebook a flight early in the day when it was clear we were going to miss my connection (we did). The seats are much smaller than I remember. I did not get the option to board early with my toddler. I was flying solo with her and that would have been a big help.

American is a steady for me. I always get what I expect from them. Sincere effort to get me from one place to another.

I am very disappointed with american. We have flown American airlines numerous times, as well as other airlines and never had such an experience. My son's flight for Sunday afternoon was cancelled around 11 am. We were told not to do anything bec AA would. After an hour of not seeing a change in his flight status. I called AA. I was on hold for half hour then opted for a call back. That call back never came. So I called again, in meantime I started looking online at my options. No flights were leaving that day from AA. But other airlines were flying out. We needed our son in Chicago asap.i kept calling AA for a callback, but never received one. Finally i called back later in the afternoon and a representative answered the call. She told me there were no flights out till Tuesday morning. I asked how this is possible, I had seen flights from AA and other airlines leaving Monday. She said she checked all NYC airports and there were no AA flights till Tuesday AM. Then I asked about getting on another airline. She responded i would be responsible for that. When I asked how AA would reimburse. She became nasty and told me AA has not responsibility to reimburse anything they will put me in a flight for Tuesday morning. When i explained he must be there Monday by 8am, she told me there's nothing to do and practically hung up. At that point I just asked her to book the Tuesday morning flight. I had this experience with other airlines, cancelled due to weather and they and their reps were much more helpful. Either way Tuesday morning flight was delayed as well. Over an hour! I expect more from AA.
