We had TSA pre check and paid to get it! They told us we would not have to do many of the things such as take your shoes off which I had to do! I’m 78 years old with NO criminal record and. they also patted my ankles down, Why? We boarded the plane in an orderly fashion only to sit there while they perform repairs to the lavatory. Why didn’t they do that before we boarded? I also paid extra to have more room because of my age but that was not what I had hoped for. I know you can’t control who sit in what seat but the guy next to me was bigger than average and took up part of my space.

We sat on the plane waiting an hour before takeoff.

Flight was cancelled while everyond was on the plane, ready for take off

Robert the flight attendant in first class made my first ever first class experience worth every dollar.

The plane boarded on time. Takeoff and landing were smooth despite the wind. The flight was too short for any food, drinks, or entertainment.

Boarding, crew, and duration were great. The lack of built-in entertainment is a turn-off, especially in this day and age. I’m also tall, so comfort is always an issue. More legroom without extra cost for taller passengers would be great.

Good, very quick flight so there was no food or drinks which is ok

The flight went smoothly, but I wore a down coat the entire time, the plane was frigid, the lead attendant seemed to be experiencing hot flashes lol, so no sympathy from her. Now, the PDX airport was another thing. It was a 12 minute walk from the gate to the baggage area, and I walk faster than most people. Seriously 12 minutes!

I purchased a flight to Hawaii, changing planes in San Diego. My flight change location was later changed to Seattle then on to Kona, adding hours to my already long flight. Also, my flight home was run through Portland rather than through San Diego, once again, adding hours to my flight. At 81 years old I don’t want hours robbed from me.

Our travels originated in Spokane to Portland, we left about 1/2 hour late, we had only 45 mins to catch the flight home. In mid flight the flight attend approached us saying that we are going to land after our plane home is going to start boarding. And not only my wife and I are on that plane, but 3 others. We ended up landing about 40 mins the plane started to board, they let us off the plane first, but when we got off the plane and started to go to the next gate, there was no one to guide us or aid us in how to get to the next gate! With that being said, the next gate was VERY, VERY far apart! We practically had to run to the next gate, which was at the end of the terminal. It was not like we took a different Airlines for both legs, but it was the same Airlines.

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?

Typically I give delta excellent reviews. Our flight was delayed 2hrs, I was one of the fortunate ones who were able to get to my connecting flight. Also, annoying that on the connecting flight boarding personnel make me put away a small bag into my carryon. It small enough to put in back pocket seat, why hold me and the line up to just push it into my carryon.

Everything was great. Great service, excellent communication, and early arrival

Delta flight attendants poorly managed the boarding process and overhead storage. My bag was checked last minute and no claim ticket was provided. My bag is now lost. Complete incompetence by all flight crew involved.

Flight was delayed two hours. No snacks and no tv screens. My bag got stuck in Chicago

Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.

Received an email the night before showing that there would be seatback entertainment on our flight. We get on and there was no seatback entertainment. And then it was a scramble to try to set up the iPads for the kids before takeoff so they could watch something for the four hour flight.

The aircrew was solid, the flight was chill, I had no issues. The gate agent was not the best. I was trying to use a military bag upgrade to move my bag from under the seat to the overhead bins and he told me there’s no overhead bins on the plane, argued with me why booking put a military member in basic economy (I don’t really understand this) and made it an issue to even try to help me stating I’d have to call reservations to get a bag upgrade. When every other agent with United can add it at the gate, this man couldn’t be bothered.

Short flight - no food understandable. Flight was delayed for over an hour. Overall, it was good.

Boarding always seems a bit chaotic. Seat spacing could leave more for leg room.

First class felt like economy, seats were horrible, food was horrible, staff inattentive

EVen warmer in the plane it think it was 24+ degrees

Good flight. On time. Boarding and seating was easy. Crew were really friendly, yet professional. Bathroom (by cockpit) was small but serviceable. Some the seats were showing some notable wear & tear, but were comfy. Very happy UA customer. TY! 🤛🏽💗

Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.

My seat was wonky...hard and not much padding. I sat next to the Jumpseat for the flight attendant. Thoroughly enjoyed not have a third seat in that row! Flight attendants were amazing. I couldn't answer the "food quality" question as there is no food served on my short flight. I commend the pilot as I know it was super gusty when we landed. Thanks

Seating was horrible. Small seats. Access to flight information and extras very iser unfriendly. Kept losing internet after paying for it. Staff in madison was as unprofessional and unhelpful.

I had a very unpleasant encounter with one man from customer service: he was extremely rude and miserable. And his condition was reflected on his decision to send me to the worst airport hotel and get an awful flight connection. My hotel shuttle had never arrived and I had to book another hotel. People served by other representatives got a much better treatment and deal.

AA is always pretty solid. Was on time all the way around today so can’t complain!

Ok. Got us there safely and a bit early. Need food available on this long flight. Almost 3 hours.

Flight was delayed by 11 hours. Flight agent finally had to rebook us, but did not rebook fully correctly. We had to pay out of pocket to get to the hotel they booked us and couldn’t check in the next day online because the next day’s agent said they didn’t complete the process the night before.

Flight was late and TSA had shut down so (almost) no passengers could get to the gate. American failed to inform TSA to stay open! Needed to get back home so we had to rent a car & drive 13 hours all through the night. It was bad.

Very mediocre greeting as we boarded, and the lead flight attendant accent was almost unrecognizable. He joked around a lot, while trying to give the safety demonstration, but did not succeed. My wife’s row was completely missed for beverages and the lead flight attendant didn’t even know that our row was Main cabin and able to have beverages at no charge. We are platinum, 2,000,000 miles on American Airlines and this was not a stellar crew.

Had to go get beer myself from attendants in the back of the aircraft

AA had a nationwide tech glitch today and after two connections snd hours of delay, I arrived 7 hours late to my destination

Boarding was very well executed. Got my bag right away.

I was surprised that all baggage, including carry on, were charged. Each additional bag went up in cost. Really disappointed in the additional costs.

Our flight was suppose to leave at 9pm and we didn’t board until after 3am. We lost a whole day at our hotel and half a day at a park we paid a lot of money for.

It was a redeye flight, so every passenger just wanted to sleep, but through the entire flight, the flight crew made announcements over the loudspeaker at maximum volume every few minutes making sleep impossible. For example: it’s 2am, and the crew decides to give an extremely detailed announcement about snacks and beverages for sale. And 3am is the perfect time to wake up everyone with a lengthy announcement about how to get a coffee refill and how to take advantage of new offer from frontier for a credit card.

Overall experience good. There was no food and seats were not terribly comfortable.

Boarding was organized and flight was on time. Overall very satisfied with my flight.

The takeoff was the smoothest I've ever experienced on any airline and this is the first time I've flown on frontier so this was an extremely pleasant surprise!

Delayed each time on a round trip with no significant weather interference. Updates to flight times came after the fact. 30 min behind in boarding and board and phone still show an on time departure. Some mysterious extra 300 miles that came so surprising they had to fuel while we were already on board?

A lady asked to stop the flight after the tunnel pulled away and we began to depart a flight that was already hours late. The attendance respectfully stopped the the plane and had the tunnel return. After the tunnel returned the passenger claimed to have changed her mind . The tunnel was then put in reverse and the passenger remained on the plane .. They should have sent the sick passenger off the plane like initially replaced. They existed a couple off the plane prior to that situation.. So.. all and all.. it was a long and flight.. .

terrible cascading delays and unhelpful customer service. uncomfortable plane. crew was great, however!
