Eva Airlines attendants were wonderful. I really enjoyed the hot meals. They always greeted me with a warm smile. I'm looking forward to flying back to the USA with them again!

Flight was cancelled which destroyed the rest of our journey.

WOuld have liked coffee or pretzels but other than that, crew and pilot and flight were great. Seat was great, too.

The overhead storage was already packed full when I boarded (I fly peasant class), but the attendant played some Tetris and made a spot for my small suitcase. Thanks!

Snacks for our toddler could have been better, front the standpoint of variety but that’s not any different from other airlines.

I fell asleep and missed my flight and they rescheduled me no problem. Staff was professional and the plane was clean. I was very happy with my experience.

The flights left both airports on schedule. The flight from Idaho Falls to Seattle was a typical commuter trip. The flight from Seattle to Maui was not good: It was too long for a flight in a single-aisle plane and too cramped. I kept asking myself if I would ever visit Maui again if airlines continue to run this long flight like a typical short commuter flight. I am not looking forward to the trip home.

Flight was on time. Staff was polite and efficient. The snacks were good - only an hour and a half flight. No entertainment but didn't expect that. We brought our own things to do.

Everything smooth (including the landing) and on time. Easy. Thanks.

The boarding in Idaho Falls was terrific. The plane was a bit sad, and the snax were subpar. Mostly, I was just grossed out by the Alaska gates in Seattle. EW! Smelly and cramped and dingy!

First The flight got delayed because one of the crew members was late and we couldn’t board until she arrived. Then we all boarded and got held in the tarmac for another 30 min.

Flight from Savannah arrived very late and we did not take off till 2 hours after scheduled departure!

No food or drink, Not much conversation with crew. They didn't come through to check on people. There were no charging stations or wifi to watch movies. It was like being on a bus in the air.

This flight was originally delayed by ~45 minutes; which is fine. However, there were additional delays due to late offboarding of the prior flight, unclear issues with the boarding process, delays on the tarmac, and exceptionally long taxiing. None of these issues were communicated proactively. Additionally, the flight had exceptionally rough turbulence, which led to a very uncomfortable flight and no traditional beverage service. Again, this is understandable, but it was not communicated up-front by the flight team.

This flight was a first class choice and left much to be desired. Seat backs on seats were falling apart and torn. Seats actually didn't come to a "full & upright position". Pull out table was sprung. Not any significant leg room. All in all we were on an obviously older plane and felt overcharged for what we received as first class.

My husband is very tall and we generally fly Delta Comfort. We used our companion benefit, and our seats were coach and extremely uncomfortable........ horrid even

I specifically picked out right side aisle seats because my left knee sometimes needs to be stretched. But my experience this trip was that the seats were shuffled and I lost those assigned seats, resulting in me having to sit in a much less desirable position for my comfort.

Other airlines were canceling flights but Delta got us home. Crew was friendly and professional. It would have been nice to have had a little more notice about the delays because we had already arrived at the airport when the first of several delays were communicated but I understand that storm forecasting isn’t simple and we were grateful that Delta didn’t just cancel the flight.

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

On time departure and early arrival. Kind and professional service from flight crew

The international portion was good. Food and beverage options were good. The sustainable wooden eatery was less than desirable. Your Star Alliance partner ANA provided real silverware. I'm 6'3" & 198 lbs and felt cramped in the exit row. How can that be? Flight attendant all had a pleasant disposition which is always good.

Flight was late to take off Plane broke down Had to move everyone to another plane Told we weren’t going to LGA but Newark Also told we would be taken to NY But United lied and we ended up at Newark at 2 in the morning Horrible experience. And the experience of trying to get compensation from United is just as bad. They could not care less about their passengers Never again!

Flight was late, the only reason I almost missed my flight was that my connection was also late.

Staff on the plane was incredible. Check-in was very complicated with no staff to help at the airport. I was charged for a second bag even though my ticket says 2 bags are free

Flight be on time would be a good start. Then train your flight attendants to be attentive and friendly. This time they completely forgot my row for the measly snack! United, do better!

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.

Read the fine print. This was my flight home. I booked my flight for the quickest way home. Had a carry-on and a personal item. Same as my outbound flight. Apparently I needed to pre-pay extra for my carry-on. When I checked in, I was told that I had to check it. I said I’ll pay for it, and was told that this wasn’t an option anymore. They said I still had to pay $50 to check my carry-on. I told them I’ll pay whatever to just carry it in as intended. I was not allowed, so eventually I paid $50 to check my carry-on under a plane that was half full, with overhead compartments that were even less full. My white carry-on suitcase was practically destroyed getting from Idaho falls to Denver to Orange County. The low price air fair was a bait and switch. Got me to the gate, made me pay extra, then didn’t even allow me to pay for a carry on. Not to mention that I paid the $8 for WiFi that didn’t work. All to get my suitcase destroyed. I don’t think I’m going to even keep my Untied mileage plus membership and card. Apparently, membership does not have its privileges for this one.

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

During landing. 2 crew members passed 3 times by my lane and didn't notice that people in front of us had their site to the furthermore reclined... That was uncomfortable and could have been dangerous.

United Airlines was fantastic, however, UnderPricer was a nightmare. I got to the airport 4 hours before my flight. We are moving to New Zealand so had quite a bit of baggage (16 checked items) and so wanted to have plenty of time to get everything taken care of properly. When I went to check in they (United) could only find a ticket for me. The 5 tickets for my children were never officially ticketed. I called Underpricer and they told me it was United's fault and United told me that Underpricer just needs to reissue the tickets, but they refused to. I asked the Underpricer agent to transfer me to his supervisor as I was not getting the help I needed. He told me the supervisor was busy but that he would call me back in 30 minutes. 30 minutes came and went with no phone call. After an hour I called Underpricer back but they would not let me talk to the person I had talked to before, just told me that he was talking with the supervisor and technical support. I called again an hour later, was told the same thing. I tried again later, with only about 30 minutes until my flight was scheduled to leave (meaning I had been at the airport for more than 3 hours with my 5 children trying to get ticketed and board the flight). Also, my husband had moved to New Zealand 3 months prior, I haven't seen him in 3 months, my children hadn't seen their dad in 3 months, we were all extremely eager to get on that flight and get to New Zealand. The situation with the tickets did not get resolved until after it was too late to check our luggage and board our flight. We were devastated. My 11 year old son was in tears at not being able to be on his way to see his dad. Thankfully we were rebooked for the next evening, but that night it felt devastating. We'd been at the airport for 4 hours waiting. My in-laws waited with me and then helped me reload all our baggage and took us home to stay with them for the night. On the newly booked flights we could not sit together - my children were spread throughout the plane. So, even though I had paid extra to select our seats after buying my seats from Underpricer only two of us were able to sit together (thankful that my 11 year old wasn't all by himself, but not happy that my 14 & 16 year old daughters were seated by strangers). I really feel that Underpricer should refund me what I paid for the seating ($120 USD). It was a very frustrating situation and I plan on never using Kayak or Underpricer ever again.

It was on time. Flight was comfortable. Staff was nice. It was the way a flight should always be.

The price was the only good thing about this flight. It was scary during takeoff when the plane tilted side to side. It made me feel very nervous as I have never had a take-off that unsmooth. There was no on-flight movie or music options and the only complimentary option was water. Other airlines offer trail mix or a caramel cookie and pop options as complimentary. This flight was a 2.5 hour flight. I understand for shorter flights not having options, but a flight 2 hours or longer should offer more complimentary options and in flight entertainment. Also the seats did not recline and for a longer flight reclining seats are a must for comfort.

A very pleasant flight but it would be greatly improved with wifi to help entertain kids

This is a no frills, get it done, efficient airline. The seat is a lawn chair. You better bring your own entertainment. If you want something other than water you need to pay for it. But they will get you to your destination quickly, on time, and then they will turn the flight around and go right back where they came from. Reliably. Couple times a week tops. If it fits into your schedule, you can’t get there cheaper or faster.

A three hour delay to board and then another hour on the tarmac because they couldn't get a tractor? Ugh.

Allegiant canceled the flight. The flight the next day was full. Allegiant did not provide any compensation besides a refund. Last time on Allegiant.

Seats were very uncomfortable and being charged for snacks and water.........

Allegiant actually impressed me, original inbound flight from PBG was so late they gave us a bird inbound from Des Moines and only left 1h late and gained 40 minutes back in the air. Comfortable flight with no frills but no complaints.

Flight was delayed. Crew was good but hot coffee was not available.

Great. No choice for n/a. No food or entertainment options

I’ve been on 8 flights with American Airlines in the last 2 months and 4 have been delayed.

The flight was ok, i understand Houston-Dallas is a short distance. The plane is really small: no TV, no snacks, but other than that, all was good. We had a bid delay but luckily it did not affect my connection

Horrific. We were delayed due a flight attendant stuck in traffic en route to the airport. Over 100 people were then stuck in Charolette. Then I ran to make my layover only to find that my connection didn’t have a plane anymore. Waited 2.5 hours without any updates. On the flight we had to beg for even a pretzel option.

Uncomfortable seats, spotty WiFi, only Biscoff for snack (no one likes those).

I had my flight of Cedar Rapids. THen Chicago to Boston. Flight out of Cedar rapids was delayed by 12 hrs. Had to drive to Chicago to catch my flight

boarding announcements werent clear/loud. Tired of those cookies. Of the 3 staff/attendants, 1 was good and the other 2 were mediocre.

Take this flight regularly. Every single week same thing. Departure delayed. Make up some time in the air. Land at ORD and then wait for gate in "L" concourse Terminal 3 for 30-40 min-which yields a very delayed final arrival. Plus I get to taxi around and see every runway and drive over the bridge (IFKYK) over the expressway 2-4 times in most cases. Change the sched of incoming plane/work with FAA to improve traffic flow at ORD/change the timing of these flights. Whatever it takes. But do better.

American was the airline that Starlux contracted for this trip. I arrived in time to make the connecting flight on American, and then the baggage-handler debacle happened. For some reason, the first class and premium economy passengers' luggage was unloaded first. Never seen this happen before. They had handlers removing the bags from the carousel for those passengers. Meanwhile, all of the economy passengers were waiting for their bags, including me. And there were a lot of bags because it was an international flight packed full. While waiting for 45 minutes, my bag didn't show. Meanwhile, an American representative showed up asking if anyone has a connecting flight to Phoenix. Of course I spoke up, and they proceeded to try to find my bag because I had to take a bus to the actual terminal to catch my flight. Which I was not informed of before I arrived. After another 15 minutes of searching, my bag was finally found with the first-class passengers' bags because they had pulled it by mistake. So I rushed to the terminal with the American representative to catch my flight, and they informed me that I missed it and could not get another flight until the next day. Of course, after being on an international flight for 18 hours, I was in no mood to hear this. Now, to be fair, there were a few American employees who tried to help me. After hearing about the missed flight, they got a supervisor to talk to. I expressed my situation to the supervisor, and she was not helpful until I asked for compensation. She agreed to get me a hotel room for the night. So I agreed, and she disappeared into her office, and I waited. And waited. And waited. And waited. While waiting, I was asked by three different employees who knew of my situation if I had been helped. I told them I was waiting for the supervisor to get the hotel room, and they said they would check. Finally, after waiting for 75 minutes, one of the employees who had asked me if I had been helped arrived with my hotel room and arranged a ride to the hotel for me. Never saw the supervisor again. It was now 8 o'clock; I arrived at 5:45! My rebooked fight was scheduled for 6:11 this morning and I have now been informed it has been delayed until 10:00. So am I happy with American? NO I'M NOT!! ;

My flight was delayed by 8 hours I arrived at airport 4hrs earlier but to see if they can reroute me to get my connecting flt to Hong Kong. They auto rebooked my flt. With no chance. Which I missed this entire reservation through kayak. My next flt they got me on was at 6 am. Misses an entire day of my trip abroad all my accommodations seat assignments were missed and missed adding my TSA precheck to my ticket as well as my vegan meal request so I didnt have meals on any of the flight....so not a comfortable experience. Please help me with accommodations upon my return.

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.
