Delayed flight. Nicest crew member was a SW pilot flying seated next to me who kindly move to seat the final passenger. Flight extra delayed. My cup of refreshment of ginger ale was so packed with ice it was literally 2 sips.

Delayed flight. Nicest crew member was a SW pilot flying seated next to me who kindly move to seat the final passenger. Flight extra delayed. My cup of refreshment of ginger ale was so packed with ice it was literally 2 sips.

For my birthday trip this was my second time ever flying, this trip was the best.

after landing, we stay 2 hours on the taxi way before reaching the gate The airline and the crew were good though

No trays in our seats, we sat in first row, purchased a business class fare. Had to hold our drinks and snack in our hands. No plugs for our cell phones. Had to pay for it a drink cocktail each. Seats so uncomfortable.

I'm not a fan of Southwest's model. I don't like the herding style of boarding.

It is southwest seat was ok. Not the most comfortable seat

Plz don't take away free bags and free seating

Gate agents were informative and friendly… flight attendants were as well. Had a fun time chatting about their legacy AirTran experiences as a former fan of the airline that Southwest acquired.

Excellent! Only question is how we check in at exactly 24 hours in advance and end up at the end of the B boarding group

It went well. Plane wasn't full. Will be great when assigned seating is in place

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

I was with one of the last zones to board. It was kind of annoying to finally get called to board and my whole section was already on the plane. Clearly they boarded with previous zones. So by the time I got on board, there were no spaces for my luggage above my head. I had to put my luggage 4+ rows behind me, which meant that I had to wait even longer to get off the plane, since I had to wait for those rows to clear the aisle before I could retrieve my luggage and exit the plane. This also held up the plane cleaners, as they couldn't service my row until I cleared it, so they were all standing there waiting for me, while I'm standing there waiting for the other passengers to clear the aisle. Anyways, I wasn't in a rush this time, so I just waited, but I could see that being a problem in the future. Now, I could have checked my luggage, of course, but coincidentally, a friend of mine on the same flight got their luggage damaged (wheel completely knocked off) and was told by the Baggage Attendant in the airport that Delta doesn't "cover wheel damage" on luggage. This was disappointing to hear. I'm glad I didn't check mine through. If it were my luggage, I'd be highly frustrated to hear that. It makes me not want to check my luggage in the future.

Great flight. On-time, comfortable, clean aircraft, and offered snacks pre-flight to plan for a potentially turbulent route. I wish there was Wi-Fi an all Delta Aircrafts but for a short flight this is not much of a problem.

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

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.

This flight never occurred because AA couldn’t get their act together.

During service there was a garbage/beverage spill near our seats that never was cleaned up. On a relatively short flight when we’re fortunate enough to actually have in flight movies available, the flight attendants pitching the AADVANTAGE credit card shouldn’t talk for the last 10 minutes of the flight so that we miss the end of the movie.

Everything was great except British airways lost our luggage that was gate checked all the way through to Italy. No one knows currently where one is and the other one may be in route to Amsterdam to meet us but not sure. If you can Hale’s it would be awesome. The website is not helpful.

Waited on the runway for takeoff for 2.5 hours. Air traffic rerouted us. The plane didn't have enough fuel, so had to go back to the gate. Had to wait for a new pilot. Should have landed at 5:22. Didn't land until 9:10. Trash flight.

The boarding was pretty easy. However, the first class seats are not lay flat as other airlines (like JetBlue) has and therefore sleeping was a challenge.

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

Would have thought that they would gas up plane before everyone got on board

Fine. On time, cabin service was fine, bag arrived. All good. Flying into DCA so did not collide with any helicopters, which is also good. Horrid incident that could have and should have been prevented.

Standard. No different than a discount carrier on a short trip.

The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines

I am very happy with my experience with Spirit Airlines. Both flights were on time. Boarding was very pleasant. Crew was very nice. Flights were amazing and we even arrived earlier than the schedule time. I am hoping Spirits keeps on having non stop flight from Ft Lauderdale to Hartford for many years to come.

you guys canceled my flight last minute and lost my luggage.

Didn't like size of seats. Found charges for checked luggage and carry on too high

Great! We boarded on time! Everything went so smoothly! The flight was so smooth

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

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.

My experience with the spirit as a first time it was OK, but the seats need a little cushion, the problem I had the most impacted me was when checking in the scales were so off and wrong. It will tell that you would have more weight, which was not true. The scale was say that it had Thirty Eight Pounds, when get in the labels when we send the luggage into the band. It says that it was overweight. I really really dislike that because the scales are not accurate. If I use Spirit and I have that issue again. That will be my last time flying with the spirit, even though I like so much to service the planes, and everything else

My experience with spirit was terrible. Customer service was terrible. Flight got canceled abruptly with no accommodations made for the inconvenience or any sort of help. I was unable to rebook a new flight.

2 hour delay due to late plane, wrong size plane causing overbooking, and people getting off and on the plane after boarding was completed.

They canceled flight. Hard to believe there was even a plane incoming for us to get on

Since you have to pay for overhead bags then they shouldn't be running out of space and asking individuals who paid to remove stuff from the overhead

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

Horrendous. I do not recommend Frontier. The passengers lack manners and decency, and the flight attendants lack professionalism. If I wasn’t in a bind to fly with 48 hours notice for a job interview, I would not have selected a flight with Frontier and I never plan to fly with them in the future.

Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.

I chose the seats when booked the flight and paid for them. However after checking in I found we were assigned different seats!

I was not permitted on my flight and had to purchase another flight ticket to Las Vegas.

It was a no frills flight. Would have liked to be able to charge my device
