Absolutely nothing flight was cancelled and delayed for 2 days. Barely a heads up I want a full refund

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Best airline! Always friendly and welcoming. Skyclub was great and loved the fast free wifi on board. I also love that you can pre-order your meal on the app!

Atlanta boarding crew at gate were filled with arrogance and were disrespectful. In flight crew showed indifference to the needs of passengers. This is about the flight from ATL to BDL.

Boarding was somewhat chaotic. Unable to evaluate crew or food/drink because captain kept them seated due to turbulence. Have no idea if entertainment was offered.

The gate area was incredibly short staffed, with one representative manning 4-5 flights, which caused a 3 hr delay in boarding even though the plane was all ready to leave. Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

It was a good experience except when boarding a female flight attendant did not go out of her way to assist my teenage daughters in finding space for their carry-ons after their compartments were full.

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

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!!!

The net issue I had was with the gate agent. We had added a carryon to our boarding pass when we checked bags. When I got to the boarding gate the agent was rude asking why I had a backpack - I said I added it - even had an orange tag on it. She ripped my tag off and swung her monitor around to show me how she was right- saying it isn’t wasn’t listed - only a checked bag. I explained again that I wasn’t sure what the issue was but I wouldn’t have an orange tag if I hadn’t added it. Then she finally checked my husband’s boarding pass and found that the agent at checkin had added my carryon to his boarding pass instead of mine. She sent me on my way without my orange tag. Was a bit embarrassing for me the tone she used with me assuming I was trying to get away with something.

Gate agent asked if I could switch seats so a family could sit together. Agent moved me to a seat in the front of the plane, no charge. It was easy. The agent did a great job.

Great seat space. However food and drink prices outrageous. Jabbing to pay for a carry on bag or stuck paying at the gate too much.

Every Allegiant Air flight I've ever taken has been delayed. This flight was delayed a full 2 hours. It was excuse after excuse after excuse. It was a flight from southern Florida. They made us board the plane on time, but made us wait for 2 hours on the tarmac. Because the engines were kept shut off, so was the air conditioning. One can only imagine how hot the air was in the cabin over those 2 hours on the tarmac, while in the hot Florida sun. Just terrible.

Actually, for the price, I'm willing to put up with a little discomfort (upright chairs) and at times inconveniences (like any airline), lack of entertainment (I can bring my own). My flight was non stop and smooth. I would fly this route again.

The flight was delayed 6 hours and we were only offered an $8 food credit. My husband stood in line to get the credit for 45 minutes and when he got close to the end of the line the computers went down.

Worst ever! Flight cancelled supposedly for weather even though we k ow of many others who flew into Bangor same time no problem. At the airport there was no customer service at all just refund and no possibility of rebook for 3-4 days. Aweful won’t fly with them again!!

It’s a budget airline so adjust expectations accordingly. Nothing is without a fee but such is necessary for tickets to remain so affordable.

No complaints. It’s a budget airline so can’t expect any frills.

My TSA number was missing from my ticket which shouldn’t have happened since it’s in my file. The on board flight attendant who was a male, did not want to help me put my luggage in the overhead bin and made a very rude comment and was very unpleasant. The good… the woman who fixed my ticket with the TSA number was excellent and I had extra legroom which was perfect.

No lounge access with “United First” ticket. False alarm about late flight, jeopardizing connection. Wrong meal. Loose power socket would not hold plug, could not charge device. In-flight access to text messaging did not work. Toilet seat on plane would not stay up.

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

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.

Great crew. We were delayed so that late passengers could get on the flight. Love the bedding in business class. Good food. Great experience.

Too bad that first class seats do not recline significantly causing discomfort

The flight was great but board was a nightmare. The gate was changed 4 times during the layover period

The experience was great and much better than the flight going out. of course I was in first class but the service was excellent

Food options were limited which is absolutely embarrassing for a Flight of this size The staff did not come around as much and I am not accustomed to such poor service from American Airlines Drinks I believe were limited to soda and water

Was as expected. Good leg room on planes - much appreciated.

I don’t think the flight attendants are happy. They do not seem to be friendly or welcoming.

Smaller, regional aircraft limits amount of overhead luggage space. At least there were jetways at both BNA and PHL. First class food service was minimal with the usual assortment of packaged snacks (nothing creative) and no handiwipes. American tries to turn around aircraft too quickly without enough time to clean the planes. WIFI service did not include TV programming.

6 plus hour delay with no explanation. No wheelchairs to transport us on arrival. Very disappointed.

Food choice is limited, entertainment better than average, seat leg room terrible
