Thw crew was excellent but due to poor scheduling Alaska Airlines routed our flight to LAX then LAX to Seattle. This delayed our arrival at the airport by at least 5 hrs and really inconvenienced us in many ways...

Thw crew was excellent but due to poor scheduling Alaska Airlines routed our flight to LAX then LAX to Seattle. This delayed our arrival at the airport by at least 5 hrs and really inconvenienced us in many ways...

It was really good and that's why we choose AA over other airlines.

We loved the extra legroom on the flight and the fact that we didn’t have any one beside us.Everything was a n time and satisfactory.

In economy, there was actually a decent amount of legroom and it was shocking to be in a bathroom that actually had a little bit of space! It was far more spacious than Most airlines are today. It was pleasant because of that.

I booked flight for my son. He had an epilepsy episode while in line boarding the plane. No refund. WTF? Never again book with Kayak.

The queue before check-in was long and slow moving due to too few desks being open. THEN, WHEN WE FINALLY REACHED THE CHECK-IN DESK WE WERE CHARGED US$70 FOR 2 BAGS. What rubbed salt into the wound was the incredible number of large bags in people’s “carry on”.

I was unfortunately placed in the middle seat. Very, Very cramped.

Seats are uncomfortable but let room was adequate. The snack is pretty weak and the staff not particularly friendly.

Flight was on time, boarding was efficient, and crew was pleasant. It would have been a nice feature to have the seatback tvs as this was a cross country flight, but entertainment is not a requirement.

Flight was cancelled just before we boarded. I had to stayed an extra night in SF and arrived one day late. Also I had to flight back JFK and not Newark since they didn't have flight to Newark until very late the following day. A real bad experience on this flight. It took me 2 days to get back home.

They were an hour late and they didn’t have my wheelchair for me

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

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!!!

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.

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

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

Our flight was delayed in Atlanta. The staff could have gave us an explanation for the delay and how long it would be.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

The experience was good and the flight departed on time and landed early

On 2 different flights the wifi was horrible and there was no drink or snack service.

Run out of snack choices. Why are the seats not padded for your butt? Are we sitting on blocks of wood or metal for $250-300 a pop? This ain’t spirit. Let’s get it together people

Safe and on time were the positives. The plane wasn't cleaned before boarding, there was garbage and food on the floor and in the seat pocket. The TV screen was small and the picture fuzzy, audio quality was poor. Seatbelt was fraying and seat did not recline properly. No charging ports near the seats,

Terrible. Flight was cancelled due to the weather in the east and sout east(florida). Did not get any compesation of any kind. According to them, it was not under their control so I lost all the money paid for the 2 fairs from Raleigh, NC to Orlando, Fl.

There were multiple delays but JetBlue tried to make the boarding and departure process as quick and efficient as possible. The crew was as detached from reality as could be, meaning: not very friendly and just doing things by the numbers.

40 minute delay before take off after boarding flight. Bright lights throughout night flight due Issues with light panels. In flight Entertainment nonfunctional

Another horrible Jet Blue experience. This airline has suffered the biggest decline of all from best to worst. TVs didn’t work (again). internet was temperamental. Boarded late and couldn’t get organized to serve snacks.

I hate their constant delays! It’s as if I cannot confidently make plans for timing when I'm traveling with them. I slept through it, so all I can say is it was good.

Did not wait long for wheelchair and attendant to arrive after checking in. Wheeled down to plane Was greeted with a smile when entering the plane Choice of snacks was very limited to 2 items. Seats are uncomfortable. My butt was sore after the 1st hour of flying. Needs better cushioning at seats.

Did not wait long for wheelchair and attendant to arrive after checking in. Wheeled down to plane Was greeted with a smile when entering the plane Choice of snacks was very limited to 2 items.

One hour delayed departure resulted in problems with planned ground transportation at my destination.

The non stop flight and able to go into Atlantic City airport. They could lower the prices. It starts out low but then if you want to bring luggage and pick your seat the price goes up quite a bit.

Flight expected to leave at 6:40 pm ended leaving at 8:00 am the following day. I slept in a cold airport. Never again Spirit for me…

My flight was cancelled!!! I had to spend 200.00 on another flight!!

worst trip ever Spirit lost our Baggs which were never put on the plane in Atlanta. 24 hours ago they are telling me now that the bags are still missing.

Horrible. Delays, no customer support and fake promises and everything. i am suffering to help as due to connecting flight getting missed no support on ground and customer support window is closed and we are sitting o ground without anything

Terrible… missed our flight due to ridiculously long time to go thru baggage check-in!

Everything was really good but the seats are not very comfortable.

Spirit canceled the flight in March and never notified me!

Pretty good. Would’ve been excellent if we would have left on time and the crew wasn’t late.

Spirit airline tries to screw you at every opportunity. Spirit wanted 65$ for an extra pound in the suitcase Made me open the suitcase at the counter to remove 1 pound. Staff very cold and rude Will never fly spirit again and will recommend same to family and friends

It was delayed 9 hours for operational reasons, despite the plane arriving to the airport on time.

I am very disappointed with Frontier Airlines. They cancelled our flight because they couldn't find a crew member, and then didn't get us to our connecting flight. We had to cancel our whole vacation. We were promised flight and hotel vouchers, but they never sent them.

Check in online was easy. Seats aren’t very comfortable

I fly Frontier because it’s affordable. I understand that the seats are tight and not the most comfortable…but that’s part of it. The problem with this flight was that there was a group of travelers directly behind me at the back of the plane who were ridiculously loud and obnoxious the entire flight. I’m pretty sure they were drunk and I could periodically smell an odd odor that I believe was one of them using a smokeless vape pen. The stewards had to remind them to keep quiet during the pre-flight instruction, but that was it. They never said another thing to them for the rest of the flight. It was a miserable.

Six hour delay. Poor customer service. No voucher. Bad communication. Missed important appointments.

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.

Flight delayed 3 times, resulting in late arrival, rental car place gave car away resulting in increased BS charges because I was late. Frontier blows.

It was impossible to change a carry-on for a checked bag after the initial selection. The flight was delayed 14 hours "to allow for a late arriving aircraft." The seats were shockingly uncomfortable. This was only the second time I've seen seats that didn't recline in an airline. The first was in an East Bloc airline before the fall if the Iron Curtain.

First time flying Frontier, I am not sure the Ala Carte menu of options is for me.

I liked getting off the plane. Everything else was well below standards. Not even offering a bag of peanuts for free for a 4 hours flight is ridiculous.
