Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Flight left early and arrived early. the whole trip was excellent.

Seats were really tight and the seat belts did not give enough slack.

I like in St George and prefer to fly out of CDC than SGU. Hopefully, they will continue the flights out of Cedar

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

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

Newer plane, relatively easy boarding, not a full flight and was told that we could not be moved up because of weight and balance issues. Otherwise, a very good experience.

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.

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.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking

No music app working: no economy meal on five hour flight; hour on tarmac at the end waiting for a gate. Flight itself was smooth and easy.

It took 1-1/2 hours to get our luggage after we landed. That to me is unacceptable

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

Overall was excellent. Will definitely us JetBlue in the future.

Very well organized both boarding and deplaning. Very satisfied with the service I received.

I rate it is good we had a 4-hour travel delay at one point but JetBlue gave out food vouchers and travel points credits for another flight so they try to make up for it

Smooth boarding and friendly crew. Unfortunately as soon as we boarded the unit that provides air circulation failed. The pilot informed us and requested maintenance technicians to check it out. The plane became uncomfortably warm without any fresh air coming in. Plus the repair delayed our departure. I am glad the maintenance crew were able to fix the problem. I also was without use of my tv monitor for the first 1/3rd of the trip.

Flight was on time arrived at the destination 10min early they kept in touch via email

This was a pleasant, short flight and the crew was friendly.

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!

It was good. It’s been a long time since my wife and I fly any where and things have changed. Our trip was to see our new grandson. We fly economy and that was not good for my bad back. It was a quick flight but uncomfortable.

I paid for what I got which was cheap, I brought my own entertainment. I knew what to expect, so I could be prepared. If you’re flying economy, check in early like me. I have no problems with my flight, was on time, staff were friendly, and overall good experience.

Boarded over an hour late, no communication, the sign just changed, no attendant to answer questions - she disappeared forever (hiding). Small plane and couldn’t hear the overhead nor understand.

Service in first class no longer exists on American Airlines .

Customer service in first class does not exist on American Airlines

I never have a good experience with American and this was no different. The airplane was INCREDIBLY hot. Like unbearably so. Everyone was fanning themselves with pamphlets and sweating. When someone asked the flight attendant to turn down the temperature they were told there was nothing the crew could do. Once we pushed back from the gate we then had to wait an hour to take off and the communication from the crew was not good. People were getting up this whole time and a man was even in the bathroom when we took off. Once we landed at our destination we waited another 30 minutes at the gate to deplane with, again, no communication from the crew as to what was going on.

Flight was delayed due to a steering issue with plane. The delay caused me to miss the connecting flight. The delay caused me to spend an extra 21 hours in airports and flights to get to my destination. The plane issue obviously should have been found and fixed before we even boarded. Ridiculous.

First, to be fair, the flight was on time and the trip through the air was relatively smooth. But the flight was full, and they were checking carryons. As this process went on, the crew got increasingly rude and overbearing. During the drink service, a young girl (maybe 9) who had gotten up to use the lavatory got stuck behind the cart. At some point, she started feeling fearful and overwhelmed. Passengers noticed this and asked the crew to let her return to her seat. They refused. Then she started crying, and they still refused to move the cart forward to let her sit. The poor girl was trying to be brave and compose herself. The crew handled the situation terribly and with zero grace or decency. That episode, to me, encapsulates AA’s attitude toward its passengers. Disgraceful. The plane itself was cramped and miserable, as usual. There was zero inflight media or entertainment, other than the lane and borderline inappropriate jokes the steward made during the safety briefing. Then, of course, it took the better part of an hour for the checked bags to show up at the carousel. AA is no better than the el cheapo airlines these days and a far, far cry from its former self.

Stop nickel and diming passengers with different seat costs, paying for water, carry on luggage, etc.

Boarding was smooth and on time. Flight itself was smooth (aside from some turbulence) and no glitches. On the downside, Spirit's no-frills service was as expected (no food or drink, cramped seating, extra cost for carry-ons, etc.), the announcements were nearly incomprehensible, and the constant niggling offers of upgrades and other services for sale (wifi, sandwiches, etc.) is annoying. Overall, a pleasant and uneventful experience - definitely worth the price.

Lower cost is the reason to fly Spirit. Should give free baggage with credit card.

From gate to flight crew... All Spirit employees were great! Everyone was kind and helpful. Ride was almost smooth... A few bumps... But no problems. Seats were tight and uncomfortable. Our biggest issue was no free drinks. I can understand paying for adult beverages and can understand no snacks on a 3 hour flight... But no drinks???? I had to pay $4 for an apple juice for my son. That's not right. You should probably reconsider that.

Loved staff help @ kiosk, staff on airplane. Commitment to punctuality. I sat in a "blocked" row, where the middle seat had no passenger & loved it! I appreciate not having to pay for water, which I've experienced even on international flights. Only negative was how dirty the bathroom was for a 4.5 hrs flight. But I don't think flight attendants monitor this.

- flight attendants not very friendly. - Paid for WiFi and plane didn’t have it working , never got a refund.

Great! First time flying with Spirit and I definitely loved it!

Not efficient. Missed my connecting flight over improper operation of spirit crew.

Very difficult. Flew out on Dec 24th and it was a mess. They know it is going to be the busiest time of the year and they had no organization. Finally they called for people going on certiam flights so they could get them thru thw line then we had to rush to our gate to get in li e to board.We missed our flight do to being stuck at the border of Mexico. They would not work with us to make an affordable price so we had to wait a day with no where to go and pay 280 more for our flights. I would think that a complimentary drink would be nice. But we had to pay 4.49 for a coke. Not an overall good experience

It wasn’t a bad flight just very uncomfortable seating wise.

The flight left over two hours late. They charged me $180 to bring a carry on. There was an error with the spelling of my name and Frontair agent lied that I would need to pay $200 for her to fix the spelling, and pressured me that if I don't do it quick I would lose the flight. I called back and another agent said it costs $75 to fix. All in all, this company is a complete scam.

Very easy with the app to board and staff skills

I took my first and last flight with FRONTIER. The seats are not able to be reclined so it’s not a very comfortable experience when you take a flight of 3 hours or longer. You must pay for your luggage either carry on or check in, so taking all this in consideration at the end what you think you’re saving your paying in services that should be included. Not a beverage in sight. . You’re seriously better off getting on a proper airline such as Delta, AA, United, etc.

After waiting several minutes to be acknowledged by 3 employees on their phones, was told we had missed our flight because the doors were closed at that literal moment. Had they given any actual service or help while we were standing there we would have been on with time to spare. More than 10 people were turned away in this fashion claiming there was no way they could let us on the plane, even though it was still sitting connected to the terminal. After the desk agents let us know they didn't care about the situation we were forced to pay more than twice the price of our original tickets as no credits were given for the price of the "missed" flight. And the icing on the cake was after being treated poorly, fleeced for another few hundred dollars for new tickets? We waited on the next plane for 25 minutes passed the "doors closed" time, letting almost an extra dozen passengers on board. You're company has lazy, disinterested employees and your lack of any real help will ensure this was the first and last time we fly Frontier. Awful.

My experience with the phoenix airport was terrible, the personnel lay the ticket counter charged me for a carry on that fit in the carry on size box, and the two women I spoke with were terribly rude and not willing to help.,,, there was one lady “candy” on the flight crew that was amazing and is the only reason I stayed on the flight at all, because the other stewards helping people to get seated on the plane were terrible

I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.

The plane was clean, the crew was friendly and helpful. It’s a low cost airline so there was no food, drinks or in flight entertainment but we didn’t expect any of these things. In the room for improvement department, they should install USB ports in seats to charge mobile devices.

The seats were extremely hard and uncomfortable, even for a budget airline.

The seats were extremely hard and uncomfortable. It was disappointing even for a budget airline.

Charging $74 for one checked bag is outrageous. I will never fly Frontier again.
