Different snack. Better coordination between terminal desk and plane for boarding. Stood in jetway for 5 minutes while plane was being cleaned by ground crew.

Different snack. Better coordination between terminal desk and plane for boarding. Stood in jetway for 5 minutes while plane was being cleaned by ground crew.

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.

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!

The internet on these planes stinks. Need to get starlink

Great people making you feel great and pointing you in the right direction always

Noting this only because it’s so unusual for delta: this was just an uncomfortable flight. The jet ridge was too hot and the plane wasn’t any better. By the time we got off the ground the AC was on but for such a short flight it was almost too late.

1) It was extremely hot in the cabin. All the passengers were sweating and it almost became suffocating 2) It was a 50 min flight but there was no service. How can a 50 minute flight not have any drink/snack service?

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 plane left over an hour late. I missed my connection going to Tokyo. They haven’t sent my bag to Thailand, where I ended up. It took me over 32 hours to get here. Very bad experience so far. I hope they can fix this and get my bag to me, within 24 hours it doesn’t look good at this time.

Not a United thing, but late afternoon departures from Denver with thunderstorms is always prone to delays.

Kayak booked this flight with only 1h 20min layover in Chicago. This made it impossible for me and several other passengers to reach this flight. Moreover, the gate closed boarding in spite of several passengers still on their way without waiting even one more minute. However, the plane departed with 20min (!) delay, i.e., there would have been at least 15 min time to let the delayed passengers board without causing any delays. I complained and as a "thank you" the attendent booked us on the last (!) flight to Indianapolis ~7h later! Thankfully, I caught the spitefulness and the United customer line rebooked the flight to an earlier flight. Although I can't grade this particular flight since I never had a chance to take it, Kayak made the mistake of a too short layover and the crew at the gate was awful.

Sitting in coach even in the larger leg space is extremely uncomfortable and the staff pay no attention.

Really delayed, no effort to support customers other than “sometimes we run late.”

It was serviceable, nothing special but nothing awful on this leg.

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.

My exit seat was very comfortable Coffee was to be purchased but sodas free 😏

It was poor a four hour delay and no explanation for the delay. What’s a 35 dollars going to do. It also made me miss my car rental,

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.

the flight is delayed, which is not uncommon but the communication was still getting hopes on reaching on time which didn't happen. When I boarded the flight it was so like unimaginably filthy. My seat belt had some sticky stuff to it like food or something from before and the space below the arm rest is accumulated dust and waste like from few months i have the pictures. Cheery on top, the airhostess was an old lady who was so bossy and mad for no reason and bossing around everyone!! worst experience ever!!

The flight was delayed multiple times due to the inbound flight arriving late, which is not a major issue. That being said, the boarding process was awful. The gate agent(s) didn't allow sufficient time for the pre-boarding passengers to get settled in and then called the four priority groups at the same time - i.e., called Group 1 and then called Groups 2-4 all at the same time. This approach had all four priority groups standing on the jet bridge from the airplane door to the gate end of the jetway for 10+ minutes in the heat (i.e., it was 96F outside and uncomfortably warm). This approach also made the actual boarding process a mess. There were multiple points of failure with the boarding process that turned a late departure into more of an issue.

Worst experience ever, extremely disorganized airline with super rude crew for first class passengers. I have submitted feedback to AA customer care online that this was my worst experience traveling in over 30 years

The baggage process at the gate was terrible. Stay was not friendly at all

My flight attendant was miserable. Bathroom filthy and the water soapy in the tea. I’d choose delta everytime.

The flight was delayed by about an hour due to a maintenance issue which later then required a change of planes. The crew was great and friendly. The in-flight entertainment did not play properly on Apple Vision Pro in a Safari browser. Although the movie trailers would play fine, the actual movies themselves just had a black screen with audio. There must be something with copy protection or something that isn’t compatible with the Safari browser on Apple Vision Pro. The free inflight Wi-Fi for American Airlines Advantage members is a nice bonus. and is great that they aren’t charging extra for things that have become basic utilities in 2026, like internet access.

DCA-LAX No screen on a 5 hour flight (almost) no food for sale on a 5 hour flight (practically) no wifi coverage or speed on a 5 hour flight I should have gotten my money back, shame on American

Flight was good, little delayed because of busy plane traffic

Flight was delayed because of mechanical. Could not get landing space which caused me to miss my connection. Messy and not organized.

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.
