Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

Seat back monitors and outlets were dead and not working.

It was a crowded flight. They did the best they could.

Service was good for such a short flight. Small plane but smooth flight.

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

Uncomfortable seats on 14 hour flight. Mediocre food. On time and great crew.

The helpful attitude of the staff, and being a wheelchair passenger everyone was helpful and understanding. The trip was made comfortable by the upgraded seat which was given without my request, that was a great surprise. Thank you Delta.

We just spent $6000 on our first trip since pre COVID and we were stranded on the runway of our departing airport for 2 hours and 15 minutes while our layover was only an hour and a half. We were told by the pilot we were next for de-icing and then got bumped by 3 other planes. Pilot went on to say they only had one guy working the de-icing where they usually have at least 2. In Rochester. In the heart of winter. Someone missed a step and should be fired. I'm not done.

Everything went well with the flight. But one of the flight attendants had on inappropriate pants. She had on an old worn out pair of sweat pants. The back seam was unrivaled and should not have been worn for work. If I had not seen her in the airport with the standard type of luggage, I certainly would not have thought she was working for Delta. Not a good look at all for representation.

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

All flights were on time and boarding was issue free

Terrible! The plane was old and you are required to connect your own device to their Wi-Fi rather than have entertainment options in the back of the seat in front of you. The Wi-Fi went out during the flight and there was only one plug for the devices every two seats. Three out of five surrounding my family did not work. The seats and spaces under them were so small I could not fit my backpack, which I’ve always brought on flights and fit before no problem. The crew were unpleasant and patronizing.

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

WiFi connected but only let you go to the AA website, not even text messaging worked.

The flight was excellent, provided that we had inclement weather. We departed earlier than scheduled and arrived early. There was a little turbulence, but nothing to be worried about.

pleased with overall experienced, but seats in coach are tight.

Don't often sit in 1st class. Our experience was great.

The 2 hour delay was frustrating but our crew did a great job getting us out quickly and keeping communication especially with the people who had connecting flights

The only problem experienced was a ground stop in Chicago due to weather. But the crew handled everything professionally. They prioritized rebooking those passengers who had connecting flights and then deplaning the other passengers. When the hold was lifted, they efficiently re-boarded all the passengers so that we could depart before our departure limit expired.

It was right on time and crew were very courteous

Their computers were down upon arrival to the airport. They were unable to figure out how to board us. We were delayed over an hour and a half.

Our original flight was delayed and we almost missed our layover. Fortunately they delayed the second flight as well due to the number of people being on both flights so we got lucky. But it was due to mechanical issues which was frustrating.
