Poor customer service, no accommodation for passengers when the flight was delayed over 5 hours.

The Air hostess were very rude on my flight from Houston to Austin . Their regular communication itself felt a they are shouting at people.

The charges were ridiculous for an hour flight and the turbulence was very scary.

Haven’t flown on SW in years. Flight was on time departing and arriving. Served vegan butter onion flavored pretzels which were bad. Coke served was in a tiny paper cup. Crew was not engaging. Felt like they were going through the motions. Old plane, tight seats and no leg room.

No delays and arrived to destination 30 min early. Staff was super friendly.

The plane arrived 25 minutes late, and the Wi-Fi was slower than it usually is.

Flight was on time and the crew was very nice.

Flight was delayed for 1 hour. Otherwise it was a fairly normal Southwest experience

Main flight attendant made light of the delay and presented some humor to lighten the tempestuous situation. Delayed flight took off 2 hours after scheduled time.

More assistance and clarity for travelers with gate checking and lap children

Good flight, loved the snacks (Biscoff cookies). For boarding, they forgot to change the sign showing our group was boarding. Apparently, they had announced it, but the announcements overlapped with another gate announcements and no one could actually hear what they were saying. So a group of us were waiting....and finally asked and were told we could board.

overall no call for accessible while boarding. The crew member was little rude not bothering about the condition. Seat assigned was very uncomfortable.

Check in & bag drop was straightforward. Alaskair changed the gate approx 40 min before departure, and I only became aware due to Google wallet update to my boarding pass. Had to move from gate N1 to C9 which required use of the Train, luckily I had time available.

Flight delayed no communication. The gate was changed so many times.

I wasn’t aware that we needed to supply our own screens for entertainment

I was standing in line to use the restroom. A First Class passenger wanted to use the restroom after me, but Jaques made me wait on Flight 3418 from BOI to SJC on December 12, 2025. I felt this was inappropriate and rude.

Look at my previous review I just wrote on this survey. It was awful!

The airline staff was great! The best safety review ive ever had!

Hawaiian Airlines, like most US-based ones, constantly provide sub-par service and pack their planes to the max with all kinds of last-minute-purchase schemes. As a result, it makes every flight so uncomfortable and generates high health risk for its passengers. In one word, GREED rules the day!

generally good. No snacks or drinks on the flight 3379 from Portland to San Jose, CA. Sad.

Flight was delayed for about an hour but overall good experience

We never made it on this flight because we missed our connection due to o delayed flight from Jackson.

The gentleman at the gate I think his name is RIE was exceptional

The cabin temperature was nice and cool. The wifi was not working.

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Crew was not friendly when I went to request a seat change.

Comfort+ on delta was excellent room for a 6’4” male. No one issues. Staff was great. Flight was bumpy but the pilot did everything he could to make it comfortable. Internet went out half way through the flight. I am glad I didn’t pay for it. But that was a huge issue for users.

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

7 hours delayed due to operational issues on United’s end. Basically laziness.

We were given vouchers we couldn’t use with a 5.5 hour delay

This was a 5 hour flight with no entertainment and with a snack being provided (pretzels and fruit bar), which are both high in carbs and sugar. Nuts would have been a better choice.

Good plane, crew, and flight. Boarding was a bit chaotic. Bathrooms were unacceptable. United DESPERATELY needs a new terminal at IAD.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

787-9 Transcon from IAD-LAX FYI no meals in premium plus, not considered Premium - seats are wonderful https://www.united.com/ual/en/us/fly/travel/inflight/premium-services.html Horrible handling of delayed flight

I was crammed against a person too large for one seat. This traveler (who I’m sure you have a record of, 21E) should be required to purchase two tickets in the future. Also, your streaming service kept kicking me out of my movie.

Patrons with larger bags were asked to check the bags when boarding. Seems like the most effective, and least costly way, way to successfully use the cramped space.

They cancelled our flight two times after rebooking us for a later flight. We never got on the plane. We found another solution by driving.

Mostly great. Only issue was with the WiFi. Halfway through the flight it was spotty and I was unable to work as I planned. This impacted my work products as I am traveling for business and it was an unexpected hindrance which was inconvenient. Flight here was amazing. For a 5 hour flight something more than a Biscoff would be nice but I’m just swinging at windmills I guess…

Delayed boarding because a flight attendant couldn't find the gate...sat on the plane for over an hour at the gate because AA couldn't get one of the planes behind us to move

Mechanical delay > Crew Time out. No communication to passengers. Crew time out was positioned as a surprise (even though it must have been know at the time of boarding that the crew would time out.

The seats were extremely cramped, with very little legroom or personal space. There was no room left in the overhead bins for a backpack, and the space under the seat in front was so limited that I could barely fit my bag underneath. Overall, the seating arrangement felt very uncomfortable and overcrowded.

As always, most AA flights that we fly are almost ALWAYS delayed and that too multiple times. Very frustrating

The small flights with Valet Luggage has a poor service

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

We were told the flight was delayed 5 times, then it was moved to the next day.
