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!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

The pilots were good. Disappointing when planes don't have electrical ports

I liked the piloting of the aircraft. Very disappointed about lack of electrical ports. Also, although a short flight. there was enough time to hand out snacks to comfort + seats as was done for first class.

I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

Delta is one of the best airlines I have flown

Made the Atlanta to Pittsburgh trip many times, with Delta no issues

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.

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

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

Crew were fine, drinks and snacks were as well but we were delayed for around 2 hrs which made our entry into Mexico delayed as well with the influx of arrivals at the same time. Sort of wasted our first day of vacation. We left Pittsburgh at 630am and did not arrive in Mexico until late dinner time.
