Flight did not have seat back entertainment and the wifi was iffy.

6.0 GoodAnonymous, Oct 2024ATL - BTR
Read more Delta reviews

Flight did not have seat back entertainment and the wifi was iffy.

The seats are uncomfortable, feels like a small seat pad on plywood.

Wifi did not work and they only served water, coffee, or tea.

Airline lost my luggage and set me back a day worth of travel due to having to stay in Denver to wait on my luggage

Great. Flight departed early and arrived early. Deplaning and baggage claim ww were quick.

The Gate Attendant @ Gate B36 was rude The flight was good but the entertainment system was not functioning as expected. The snacks were ok but could be better The flight crew was excellent.

Had us delay to fix forward restroom only to have stop working so I had a line of people's rear. The entire flight.

cancel my non stop flight for no reason. And force me rebook 2stop flights automatically then get short time to catch my flight from Atlanta to Charlottesville. We missed the flight then ask me rebook again to another city Richmond which far away 90mile from Charlottesville. Spend all day for flight and spend Uber from Richmond to Charlottesville airport cause my luggage was sent to there earlier half day and my food was bad cause heat. Damn delta

My flight was cancelled twice and the third time I tried to rebook it online I cancelled the flight because it looked like I would get a refund to my credit card. Instead I now have a credit. I was also on hold for three hours waiting for a representative and then disconnected. I will never fly delta again.

I know it was not in Deltas fault. But numerous delays and cancelations. I requested a hotel voucher and was told they weren't available. The lady on my hotel shuttle did receive one from American. Why the difference?

RE Food: Wish there was a choice for No Rating. Flew from Honolulu to Los Angeles on a Red-Eye flight (11:00 pm to 7:30 am). Other than a package of cookies with a beverage choice offered soon after take-off, and a beverage choice shortly before landing, no other food choices were offered. Everyone slept or rested for most of the trip. Nothing to rate. RE Entertainment: Everyone was sleeping most of the flight. Only saw one passenger watch about 30 minutes of entertainment on his iPad. I never attempted to access any entertainment options.

Baby cried a lot. Nothing anyone could do about it. Just part of flying.

For coast to coast travel the A321 and even the NEO, even in first class will never be excellent. That would take a B787 or 777 to accomplish.

The flight crew was fantastic! Which the seats had a small TV.

The foot ottoman cushion was missing on my business class seat.. the hydraulics is on its last leg & seat cushions do not have support or paddling. Heavily dented by butts

also wi-fi never worked attendant said satellite coverage is spotty over water ..... but we were over land!

I was unhappy with having the seat I chose changed at the last minute. I was moved to an aisle seat which did not recline and was next to the bathroom. The bathroom odors made the flight entirely unpleasant. Having carefully chosen my seat months before I was not pleased with my AA experience. In addition, they ran out of tea during flight service, really?

Dallas Hub. American taking ownership for their screwups instead of blaming their contractors and customers, trading their people, their call in service, reservation agents and their ticketing process. Make sure wheelchairs are available especially when the request is in their record.

The aircraft was on-time and plane and lavatory was clean.

American Airlines actually put me on a Delta flight. They didn't have to do that. They could have offered me a flight the next day or even two days later. But, American Airlines agents put me on a Delta airplane from Atlanta to Sao Paulo, instead of going through Miami when my flight to Miami was cancelled. American Airlines made sure that I got to my destination on time. I appreciate that.

Paid extra for a “comfy seat” which was anything but!

It was cancelled unexpectedly so we rented a car and drove home.

Everything that was available was excellent. Spacious and comfortable, with lovely and helpful crew (one was having a bit of a sour day, but that happens). We sat on the tarmac for one hour and seven minutes waiting for our gate to clear in SAN, but the pilot kept us informed and, amazingly, was very professional in not ragging on the airport (whose fault it was).

Flight was delayed 8 hours so far. Don’t expect to fly when choosing Spirit Airlines. I will happily pay more to never deal with this company again.

This airline is effective for the price you pay, do not expect anything extra at all. You have to pay extra for seat assignment , carry on luggage, food, you name it ...and even if you pay extra for better seats they do not recline.

4 hours delayed. once we got boarded anotger hour and a half delayed

Got on quickly and easily. When it turned out the other two seats in my row would be occupied, a nearby flight attendant immediately let me know that I could move one row behind me since it was an empty row, I moved into the window seat where I could relax enough to take a little nap. Can’t ask for much more.

I’m not a fan of Spirit Airlines from a not-so-good experience the last time & I swore I would not fly this airline again- bc they charge for EVERYTHING. I only flew Spirit this time bc it wasn’t my choice. I decided to use a “Mystery Ticket” bc of the great price, not knowing it would choose this airline! I found out on this trip how they pick a random seat with a “sticker” for a prize-are we in first grade? just doesn’t seem right & now the first 3 or 4 rows get special treatment-we all paid for our tickets, not just them.

Horrible airline with terrible customer service! I was at the Atlanta airport going to Ft Lauderdale. They delayed the takeoff time several times. We finally boarded & taxied away from the gate where they had us sit in a hot airplane for an hour & a half before cancelling the flight due to weather. They did not even offer us water. They took us back to a totally different gate where they said agents would be available to help. Instead, they dumped us out & left us to fend for ourselves. We had to go out of security to go pick up our checked luggage & wait in a long line at the ticket desk where only one agent was working & by the time we got to the front of the line over an hour later, all the flights were full for the rest of the day & only limited seat availability for the next day. If you were one of the lucky few that was able to reschedule the same day flying to the same or a different airport, you had to go back through security & ride the train to get back to the correct date which took over an hour more. A total waste of time. I will never fly Spirit Airlines again!!

I liked the airfare price. Seats are not very comfortable. But I would fly again with Spirit for the price.

Stop changing gates at sfo. When you are elderly going back for it’s not fun.

There was no easy way to check in. I don't want to install an app to checkin. I will use alaska from now on because they have a web check in method that is easy.

Horrible! The short distance flight ended up taking 5 hrs! There was a 3 hr delay for the flight to take off and there was a 70 min wait on the tarmac for some bogus reason that the pilot said the gate he was supposed to board was taken up. After a 30 min wait he said the plane that was supposed to push out of the gate called a medical emergency and 40 min later he ended up boarding another gate. For the initial 3 hr delay there was no information/alert about the gate or delay in the app or the boards up until the boarding time and even beyond! Had to walk all the way to the end of the terminal to find the frontier staff to ask what was going on. Avoid this airline at all costs! If you have carryon bags or checked bags , their prices come equivalent to the prices of more reliable airlines. They are the worst in timeliness at 60% (reported as delayed) this year (check the data) by a high margin even compared to the second worst airline. If you are ok with having a miserable flight experience with the odds close to flip of a coin, feel free to try them. If you value your time , money and flying experience, stay away.

Delayed for two hours due to trivial issues. No reimbursment. Also on arrival further delay due to terminal malfunction.

I went to the Frontier counter in San Jose at 1030am or so on Sunday 10/13/24 to see if I could get an earlier flight to San Diego in lieu of my reserved 630pm flight. One thing led to another, and I was able to obtain an open seat for about $ 56. on the earlier flight. Fine. Then the agent asked if I "was checking a bag". Not knowing that carry-ons cost extra per Frontier policy, I thought that she meant a regular checked bag. Therefore, I said no. Once I got to the gate, the same gate agent who sold me a ticket told me that I had to pay $99 for a carry-on, and that all bags were extra on Frontier. Having never flown on Frontier, I was not aware of this. Part of the issue was that she was not a native English speaker, so there was a miscommunication as to what "bag" meant. I would have preferred for her to have clearly let me know at the front counter that any bag including a carry-on cost $99. It would have had the same outcome, as I had to take my carry-on. But it got hectic at the last minute at the gate itself. The baggage policy should have mentioned "including carry-ons" when we first spoke.

Most horrible airlines. Please avoid it. It's ok to spend $50 extra for delta, united or Alaska

The personal at boarding are rude and try to steel people with their rule of personal item , really bad experience for us

The trip was good but the last minute changes I didn’t like because I had already talked to the attendee and they didn’t help me with my ticket I was having trouble checking in and when the time was up they help me but charge me for that and last minute luggage it was a small bag. After I was in the airplane I realized you were charging because the flight was almost empty and you have to get the money some how. Thanks for everything.

There were a lot of issues at the gate in Atlanta — which caused delays in boarding and getting to our destination. The aircraft and crew were excellent.

It was fine. The flight was delayed for 3 hours. I had things scheduled in Detroit, and I let a lot of people down by not being there on time.
