Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗

Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗

5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.

Great flight! Only complaint I had was that I didn’t get breakfast that morning because I don’t eat eggs for breakfast.. I ate an energy bar I bought in the airport which I had never done before. Otherwise, another great Delta flight!

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

My flight was 6 pm 6/6. Every hour they delayed it again - air condition issues then no pilot then the crew had worked too many hours and cancelled the flight at 11 pm. Sent customers to NJ a 45 minutes uber ride to a hotel. Had to be back by 5 am for a 7 am flight and again no pilot etc with another three hours of delays.

The entertainment and wifi mostly didn't work on this flight.

Terrible entertainment system - kept freezing and audio kept cutting out. Snacks were mediocre at best for a 5 hour flight.

The check in and bag drop off for Sky Priority members is slow. The Clear security was also slow - a TSA issue.

I am still upset that my bag was lost on a recent trip to Rome ; we were inconvenienced and out €150 Euros ; delta has refused to reimburse us

Most miserable flight ever. We waited almost 2 hours on the runway because the flight was oversold. American offered $1200 credit. Then there was some nonsense about weight distribution. Ridiculous. No food for 8 plus hours on the flight. I will be writing a letter.

Honestly, I haven’t flown American in years, probably due to the pandemic and my being unable to travel for certain periods in the last two years, but it was a good experience to dig out or obtain a new American Airlines account after many years of traveling for business with American in the past.

It’s a great flight. Service is good. Staff is awesome.

Again flight was awesome except British Airways lost both gate checked luggage’s. Still missing

Everything about the flight was lovely…We left early, arrived early, cabin crew were efficient and helpful. Flight was easy and most pleasant.

Everyone was nice. It was on time and the food was. Airplane food, but not horrible

One bottle of water and a package of cookies for comfort plus. We had to literally beg a flight attendant for an extra bottle of water later in the flight due to feeling dehydrated.

late again! but its my only option to not take 9 hours to get to Memphis

Almost everything was outstanding. First, we boarded on time and the flight crew did a great job getting everyone seated. Then the pilots took their time and care to make sure the plane was full de-iced three times as there was a bad ice storm a few hours earlier. The plane ride was smooth and comfortable and even the economy seats had decent room and comfort. Flight Attendant Lisa went above and beyond to make sure I was comfortable - she is outstanding. The only thing wrong with the flight, and it is something which needs to be addressed, is that the gate to gate time was over 6.5 hours and not one meal was served. The only thing offered to eat were two small cookies for a transcontinental flight - unacceptable. Charge me more but give me a meal for a long flight. Thankfully Lisa found something for me.

Very poor. Our special services attendant gave us incorrect information. I also was mishandled at landing. There was no wheelchair waiting. I fell deboarding the plane. Appalling!

Boarding was a breeze, however, two of the flights that I boarded with Spirit did not have Wi-Fi available.

Seats uncomfortable, hard to check luggage, etc. It was like the last flight out of Hanoi

Need screens for tv/movies. Seats are more cramped than any other airlines. Seats are hard. They don’t recline. And in flight time should not be used for sales pitches.

Good experience except for the drunk woman who was with a child. Sad

The ease of booking the flight was very good. Speaking with customer service was also good. However, the crew people are unfriendly and unwelcoming which I found this as unprofessional. As far as comfort it was mediocre. This was my first time flying Spirit and I chose them because of the flight times met my needs and my budget. However, I would be reluctant to fly on Spirit again. In addition, if the crew were more friendly and at least appeared somewhat happy and welcoming personally it would probably make the experience of flying with Spirit better.

Tell them to chose a better, less bumpy route :( my seat had no window all the way at the end 😔

Seats too hard, too much lumbar. Space between rows was extremely tight, so tight hard to place item under seat in front of me. No tv screens. Zero plugs for charging phones. Too many sales pitches

Prepaid for 1 bag but my prior airline did not provide it to me in time to check it with Spirit and I could not get my $75 refunded.

Plane delayed which seems to be the norm with spirt. Everything is an up charge. I had to pay an additional fee because I was late getting back to my car. Will never fly spirit again

It was horrible. We were not allowed on the flight by spirit staff at the gate during boarding because I had a guitar. The same guitar I had at check in which I paid for and they said I can take it on the plane. We missed our flight, lost our luggage, and had to pay another $900 to rebook flights. Worst travel experience ever and spirit staff are the worst staff ever.

Book with frontier airlines with the mentality that they'll cancel your flight, kick you off and lose your luggage. Anything besides that is a win. Compare prices with other airlines (to include luggage) and if frontier is still worth it, book it but know all of their policies.

You get what you pay for nothing essentially but a hard uncomfortable seat that doesn’t recline and kids screaming all around you and chaotic boarding and limited check bag weight allowance when compared to other airlines

I never got to experience the flight because they delayed my first flight and I missed this one. Then Frontier didn't want to help me rebook a flight to get me to my final destination.

The Boarding process in Denver was chaotic, and since the line was so long, we were lined up very far from the gate. If there were any announcements from the gate staff, we didn't hear them. The flight attendants were spectacular. The only negative part of the flight was sitting by a 2 1/2 year old who was unruly and unfortunately had parents that matched his behaviors. Also, the restaurants in Denver on the E concourse, they didn't have food (passengers could only order 1 item on the entire menu) or the restaurants had 12-14 people waiting for orders to be prepared and another 6 people waiting to order. If you have a layover in Denver and need to grab food, be prepared to visit the shops with pre-packaged sandwiches, or you can visit another concourse but it may take a while to transit throughout the airport.

I liked the turn-style feature at gate 209B at LAX. Very efficient process. The gate staff also made several, clearly directed announcements so I felt very informed.

Although an hour and a half early was told by staff at check in they had overbooked and could not check us in for the flight.

The crew was delayed because they came on another flight that was delayed due to weather 10pm flight left at 1.30 am The airline made no effort to align alternate crew

I liked the price of the flight and the chance to buy a seat with no person seated in the middle seat.. Also the flight was right on time.

Plane was down graded and I lost my uncharged exit row with more leg room. No mention or offer of refund from podium. Flight attendant was nice to explain this happens often and that I could request a refund via online form submission. I did this and have heard nothing back.

Worst airline experience. They were rude and kept changing our seats and/or giving our seats away so our family didn’t get to sit with each other. Almost everyone we dealt with at both airports with this airline was rude. The app kept giving us wrong information making things take longer. Dealing with them before TSA can take close to an hour…longer than I’ve ever had to deal with before. Never using this airline again.
