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

I’ve always loved Southwest. No issues at all. I was flying standby and the gate agent was extremely friendly and helpful. Boarding was smooth and I was able to get a window seat in the emergency exit row. Crew was fantastic! They were very professional and accommodating. We had to divert from our destination due to weather but the flight crew kept everyone at ease and informed us of all pertinent information. Excellent flight

The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.

Plz don't take away free bags and free seating

The seats were a bit cramped and worn, but otherwise okay.

I would have liked to arrive on time - not 5 hours late!

After a 3 hour layover in Denver my flight was delayed over 5 hours! No explanation; no assistance; no offer to provide compensation; no one at Southwest was willing to offer any assistance. 8 hours in the Denver airport - ridiculous!

It was a perfect flight in all aspects! Both legs!

Only one drink pass through the cabin for a 4 hour flight. Quite rough and bumpy landing.

Boarding process, crew were good. But the seats were so uncomfortable that was all I could focus on. I literally had to sit forward so that all 3 of us could fit in row. I will try to avoid Southwest in the future for any flights over 60 minutes.

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

Delta flight was on time, seats were comfortable, and crew was nice.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

Terrible. The flight was delayed two hours due to weather. Then when we got on the plane, the first pilot ended up timing out and we had to wait for a second pilot. Second pile came on board and we tax it out. Had to return back to the gate because of an unruly passenger. Then the copilot timed out. Had to wait for new copilot. Also had to wait for maintenance to check for fuel. Then found out the second pilot timed out and we had to wait for a third pilot. Was ready to go and then needed maintenance again for another issue. In the end, it was 2 o’clock in the morning when they announced that the flight couldn’t go because the third pilot and the second copilot had timed out.

American Airlines initially postponed the flight. Then they cancelled it an rescheduled us on a flight that would take over 24 hours with multiple stops. They then changed this flight to a reasonable alternative the next day which they later cancelled and replaced with a flight that would take off with an additional 16 hour delay. They blamed weather but I noticed (at 4am) that Delta had direct flights from Charlotte to Detroit. I went on line. Booked it and was in Detroit buy 9am. The interesting thing is they did a similar thing to a family member just 2 days earlier. I don't think I will fly American unless I have to.

I was a little disappointed of not having an android charger. Only one it was for an iPhone. I've flown American in the past and had access to one.

At least it was a short flight. Greyhound with wings.

One of the best flights I’ve had. So smooth.

This flight didn’t happen because AA agents didn’t let us board the flight

Checking in at the counter was very disappointing. The lady had a very bad attitude and smart at me. She had no smile, did not greet me by name, or acknowledge me as a valued customer. Poor reflection of the airline.

First class flight attendant was rude and lacked any customer service skills.

Paid for a window and was assigned to a middle seat with 2 very large people on each side of me. Flight was sold out and I feel I need to be refunded foe paying for a window seat and being put in a middle one..

Would have been good to have a meal since it was a 5.5 hour flight

I mean, it’s Spirit. But it was frustrating to have our flight canceled, get bumped to a later flight, and then Spirit was unwilling to check our bag until 4 hours before our flight… tell us we could not sit in the waiting area’s chairs… and really negative experience getting checked in and dropping the bag.

Not having it be changed after we bought the flight tickets from a direct flight getting in at a reasonable time to a connecting flight red eye of 9 hours, so that we would lose our 35 dollars in nonrefundable insurance would've been great! Our country really does need low-cost carrier options, but this type of "service" ain't it. Fortunately, had a little better success with them flying to and from San Juan PR last month at least.

All was good expecting the seats need a bit of cushion. Besides that I can’t complain.

You get what you pay for, and the flights went smoothly. There’s no reclining chairs, no screens, And there isn’t always wifi, but the plane was clean and staff was friendly and the takeoff/landing were smooth.

The only positive is that the flight made it both ways. Getting charged for every little thing after the cost of the ticket itself is comical, considering how the plane and services are as bottom-tier as possible. The self check-in kiosks are useless. It’s nice to think that you can print your boarding pass, tag your checked bag, and then just drop it off. But no, they still make you go through the line once you finish- what’s the point of the self check-in then? Any questions for the staff seem like the biggest inconvenience and were met with condescending responses. This was my first and now last time ever flying with Spirit. After all the extra costs, subpar plane and staff, I see no value. I’d rather drive the 13 hours than give Spirit another dime.

The flight was fine however what started as a reasonable priced ticket could have become an overpriced ticket with additional charge for carry on as well as checked bag $79 per bag per person each way. Additional charge for choosing one’s seat, additional charge for beverage and snack, we were on what was described as a new plane yet there were no audio/visual on the jet. A bare bones service but not at a bare bones price. Will think twice before flying Spirit again. 😕

Flight was delayed a bit, but that was expected (and updated), so really not bad at all for the price. Could’ve used one less email asking me to upgrade my seat; otherwise no significant complaints

I love Spirit. New aircraft, great cabin service, the airfares are low cost which helps me visit my hospitalized daughter anytime I can without paying a fortune.

Flight was 2hours late they had no crew or the pilot.

I paid for streaming wifi and the connection was poor.

The reps working at the airport counter were dumber than a second coat of paint.

My costume jewelry was stolen out of my bag. Got to airport and my bag weighed 45 pounds- 5 pounds over cost me $100 Long lines in tier one. No entertainment No WiFi no free drinks or snacks

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

The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.

The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.

It was a short flight so no food or entertainment….

Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.

I’ve never traveled on Frontier before. If you want basic, no frills, friendly service at great prices then give them a fly!

Cancelled and declined to find alternatives Earlier flight is 2 days later Sent the cancellation notification very late, wish I knew earlier would have stayed to watch the Miami open final game Very disappointing service

The worst flight of my life. Never will I fly frontier again
