Airline itself is great. While food was being taken off of my tray my beer spilled which was a total accident and I wasn’t upset about that, what was frustrating was I had to ask for towels to clean up and wipe my leg. It would have been left as is if I hadn’t.

Airline itself is great. While food was being taken off of my tray my beer spilled which was a total accident and I wasn’t upset about that, what was frustrating was I had to ask for towels to clean up and wipe my leg. It would have been left as is if I hadn’t.

Bars and restaurants in Taipei close early. The lounge isn’t very good, but better than the public areas.

Short lay over. Seat assignment was terrible. Was traveling as a family and end up being seated separately. Will not use underpricer ever again.

Unable to set seat assignment. Got a call from presumably “China airlines representative” but was asking for an exorbitant amount for the seat assignment. Was traveling as a family end up being assigned to different seats as a result. Will never use underpricer again.

Not many selections for entertainment. Bulk head seats are no longer available with out fee at the counter. That’s pretty lame.

I would have liked to know how to order a special meal (for medical purposes) before the flight.

The flight who provided services on my row had some not-nice attitude and not smiling at all.

My flight to Los Angeles was canceled Had to book another flight and you charged me extra $500 Very bad experience

Comfort was left wanting due to such a long flight, made the wife and I wish we could upgrade the seats to Business class or First Class, but did not have that option. Food was good but had very limited options and I have a dietary restriction which was difficult for the staff to accommodate since everything provided came with cheese on it. (Cheese could potentially kill me) Did not have an option to inform the staff until we were already in the air about the restriction and was not provided another option before flight departed.

Decent flight, staff was very good, especially with the turbulence during the flight due to weather. Comfort was about par with other airlines but since it was a quick flight, was not much of an issue for us.

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

New boarding doesn't make sense. Filling front first is slow.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

Not pleasant. We arrived several hours late and my friend and driver were waiting for me a long time at Tucson airport. At first we had to divert to phoenix due to shitty weather. Well, i guess I can’t fault anyone for that. But then when they refueled , they overfueled and we had to wait even longer for the plane to burn off excess fuel. So someone really screwed up there and should get fired. Human error is really inexcusable.

My seat was changed at the last minute and I was moved to the last row, right next to the bathroom despite selecting my seat well in advance. I was also made to check my carry on due to space but when I got on the plane there was significant empty overhead space. Picking up my carry on from the luggage carousel added time to my trip which had already been extended due to delay.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

There was a loud squeaky sound the whole time we were flying.

Everything was great except for the seat. The backrest would not stay in the upright position.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

It was fine. The flight attendant appeared to be in a bad mood but everything was fine.

Seats are outdated. Entertainment relies on personal device. Boarding was delayed due to inaccurate passenger tracking, resulted in late arrival at Reno.

Excellent staff helping my 96 year old senior promptly with her oxygen needs

The crew and flight was amazing. I haven't flown United in years but plan to switch to you being my main airline

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

I am not an electronic savy. I don't know how to maneuver the APPS for services. Why can't I just buy food without the apps.

This was a short flight with no food. The attendants were great but the comfort was poor: just to cramped. The flight from Denver to Frankfort was excellent! Seating was roomier, food was good, service was good. This was a great experience.

Flight was quite late as there was no pilot Crew is usually excellent, this flight not as good as usual there were more mistakes, slower and less friendly service But honestly the aircraft was too cramped and uncomfortable for a 4 hour flying get so, do to the aircraft liability the very best you could ever do is mediocre.

Flight was ok. Unfortunately it was a Boeing 737, which is a cramped / tight airplane. I prefer the Airbus as they are a more comfortable flight experience.

It was exactly what I expected, actually arriving sooner than scheduled.

VERY disappointed at the agent checking in my luggage. I know that the weight limit is 23 kg, a little over 50 pounds (50.71 pounds). Yet the agent kept repeating "50 pounds". So I said, the limit is 23 kg, and she had the audacity to say 'no, it is 22 kg!" Imagine my surprise. Was she ignorant or was she poorly trained? Not sure. The boarding process was pretty good. The speakers were loud enough so I still could hear them despite inconsiderate passengers continuing to speak while the announcements were going on. During the flight, the teenage girl sitting behind me kept pressing her feet to the back of my chair. I turned around several times, yet she did not get the hint. I did not make a fuss since I sense I had a bad streak that night with AA, so I just did the best I can to lean forward and not let that bother me.

Delay 14 hours! Missed all connections and had to fly different airline the next day.

Excellent. Attendants served preflight drinks and were courteous and nice.

It was perfect in almost all ways. In fact it arrived early in both legs of my flight. The entertainment was marginal, but that was due mostly to the length of the flight. I love American!

American dropped the ball on this flight. It was canceled after waiting on the tarmac for 6 hours. American airline was so greedy that they open the door after close, delayed our flight then caused the pilot to over 14 hours limit if they were to fly to Phoenix. So more delays and finally flight canceled. Horrible experience with American Airline in Philadelphia.

They took away my first class ticket for my plane ride from Ickx to Tucson because they’re plane was late getting there. They offered me nothing in return

Terrible customer service playing as usual was late and the Denver tried to get to a bus, but it already scheduled for service to Fort Collins, but because they could not help me at all at the baggage service desk. I missed the bus by one minute after they kept me arguing about how to handle my bag which have not gotten onto the carousel, Customer Service and Denver at the baggage claim customer service had the nerve to say she did not fly the plane and the responsibility of the bag was all mine. Pathetic.

Flight was 1/2 hour delayed leaving Phoenix. Otherwise it was an average flight. Flight crew on this trip was very nice.

Flight attendant was incredible. Very efficient, friendly and pleasant. Patricia was one of the best I have ever seen. Please give her a big raise!

Stop changing gates at sfo. When you are elderly going back for it’s not fun.

We understand and comply with Frontier’s bag sizes. We’ve had some problems in past while having to await other passengers who do not understand the baggage restrictions or have not prepaid and that is usually our biggest concern (others delaying us) with flying Frontier. Flying OUT of ONT, however, has always been a great experience. I’ve also noted even on delayed Frontier flights very knowledgeable pilots who manage expectations well.

There was no easy way to check in. I don't want to install an app to checkin. I will use alaska from now on because they have a web check in method that is easy.

Horrible! The short distance flight ended up taking 5 hrs! There was a 3 hr delay for the flight to take off and there was a 70 min wait on the tarmac for some bogus reason that the pilot said the gate he was supposed to board was taken up. After a 30 min wait he said the plane that was supposed to push out of the gate called a medical emergency and 40 min later he ended up boarding another gate. For the initial 3 hr delay there was no information/alert about the gate or delay in the app or the boards up until the boarding time and even beyond! Had to walk all the way to the end of the terminal to find the frontier staff to ask what was going on. Avoid this airline at all costs! If you have carryon bags or checked bags , their prices come equivalent to the prices of more reliable airlines. They are the worst in timeliness at 60% (reported as delayed) this year (check the data) by a high margin even compared to the second worst airline. If you are ok with having a miserable flight experience with the odds close to flip of a coin, feel free to try them. If you value your time , money and flying experience, stay away.

Allowed me to chose my seat without extra charge (I purchased full-price ticket) and boarding was in group1. Didn't even serve water.

I went to the Frontier counter in San Jose at 1030am or so on Sunday 10/13/24 to see if I could get an earlier flight to San Diego in lieu of my reserved 630pm flight. One thing led to another, and I was able to obtain an open seat for about $ 56. on the earlier flight. Fine. Then the agent asked if I "was checking a bag". Not knowing that carry-ons cost extra per Frontier policy, I thought that she meant a regular checked bag. Therefore, I said no. Once I got to the gate, the same gate agent who sold me a ticket told me that I had to pay $99 for a carry-on, and that all bags were extra on Frontier. Having never flown on Frontier, I was not aware of this. Part of the issue was that she was not a native English speaker, so there was a miscommunication as to what "bag" meant. I would have preferred for her to have clearly let me know at the front counter that any bag including a carry-on cost $99. It would have had the same outcome, as I had to take my carry-on. But it got hectic at the last minute at the gate itself. The baggage policy should have mentioned "including carry-ons" when we first spoke.

Most horrible airlines. Please avoid it. It's ok to spend $50 extra for delta, united or Alaska

Every day about it was very different all the boarding pass where all wrong l miss flight no refund all crazy

Staff members pretty horrible when boarding. No care for customers

The trip was good but the last minute changes I didn’t like because I had already talked to the attendee and they didn’t help me with my ticket I was having trouble checking in and when the time was up they help me but charge me for that and last minute luggage it was a small bag. After I was in the airplane I realized you were charging because the flight was almost empty and you have to get the money some how. Thanks for everything.
