The flight was late. The crew was rude. There was no food. Cramped and uncomfortable. Nothing about this flight was good.

Flight coming out of Buffalo was delayed, so we had to be rescheduled on another flight from Baltimore to Phoenix which means we had a long layover and got home 3.5 hours late. Shuttle to parking stopped at 10pm, so we had to pay for an Uber to the parking lot and got charged an extra day of parking since it was after midnight. Not the best experience. Long day!

Plane was clean and comfortable. Flight attendants and gate staff were professional, friendly and efficient. Boarding and deplaning were orderly and efficient. All in all, the typical excellent Southwest experience.

The lead steward kept singing about "San Francisco" and hotel California---more annoying than humorous....needs work. Flight was smooth and on time.

Airline travel is always too cramped to really be pleasant, but the cabin crew on this flight did a pretty good job of making up for it by putting on some music during boarding and sprinkling a few funny remarks into the safety briefing and announcements, and just generally being friendly and helpful. It definitely reminded me of why I prefer the in-flight experience on Southwest!

It went well. Plane wasn't full. Will be great when assigned seating is in place

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

Can not wait for seating change to reduce the amount of pre boards - it’s disheartening the abuse. And then then deplaning

Flight was delayed more than 2 hour do the scheduling issues and then some confusing weight and balance matters, followed by a miscommunication with the tower on which runway was going to be used based on the airplane weight. All these things should have been figured out in advance. Instead of arriving at 12:30 a.m. we arrived at 2:30 a.m. very difficult to find a taxi or other transport at SFO. Luggage was delayed. An extension of an unpleasant flight day

The crew was fabulous, outstanding, friendly, attentive and just great, really made my flight one of the best I've ever had, thank you southwest crew flight #474, from Los Angeles to San Francisco on April 2,2024

We sat on the runway for over an hour before departure. That was unwelcome.

Everything went smoothly, although the usual gripes about airline travel were still present: the boarding process is inefficient, the snack selection is limited, and so on. Since there was extra space on the flight, the gate agent rearranged many people's seats to put people on the aisles and windows, leaving the middle seats empty, as much as possible, which was pretty great.

One of the flight attendants was a little cranky. I appreciated the free wifi and plug to charge my laptop

WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.

Generally on time departures and arrivals, clean planes, sky miles membership provides great benefits (complimentary upgrades, etc).

my mom urmila patel needed a wheelchair which was not available on the curbside. she needed to walk almost 50 meters inside (at the risk of falling) and then had to wait in line to get a wheelchair (this is not ok). Once obtained she had to seat in it for 30-45 minutes for someone to take her in thru the checkin process (which was fairly smooth and easy). the lady who helped her with her checkin process was very courteous and helpful

I usually get upgraded so my experience is usually amazing. I did not get upgraded this time - which was fine - but the wifi had issues, the monitors were going in & out, & (though not Delta's fault) one of the gentlemen next to me desperately needed a shower.

Terrible entertainment system - kept freezing and audio kept cutting out. Snacks were mediocre at best for a 5 hour flight.

I am still upset that my bag was lost on a recent trip to Rome ; we were inconvenienced and out €150 Euros ; delta has refused to reimburse us

Really impressive staff at airport and on plane, especially given how busy it was

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

First class ticket gets you no seat back entertainment? I have to bring my own laptop to see a movie? And most of their movies have ADS? No thank you. Worse: Tiny snacks only on a 2 hr flight?

Late plane. Only one crew on the ground so we b had to wait for Denver flight to come in, board, and depart. At 78 yrs of age I was not pleased trying to get my connection. What really made me angry was the notification you sent me to hurry up or I would miss my connection. Why tell me to hurry up when you got me in late. It was not a good way of treating customers.

No complaints other than luggage carousel was incorrectly guiding passengers to the wrong carousel on the screen.

The flight was delayed from take off because only one runway was operational in San Francisco.

Several missed and almost missed connections. It felt like everything was being patched together last minute without enough resources and it ended up being an extremely stressful experience that basically ruined our weekend on the west coast. What a waste.

Was put into a seat right behind the toilet that had no entertainment possible but did have plenty of leg room over noisy part of plane.

Flight: Started on time. Comfortable flight. Arrived on time. Crew: Very cordial and helpful. Drinks and snack was served with a smile. Overall enjoyed the trip. Regards, Hari Doss Chanchala Doss

A first class seat should fit a fat person, and this doesn't. The trays in the armrest are less functional than an ordinary tray in the back of the seat.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

This was a horrible experience. For a first class experience, my chair was held together by 3M tape - and I have a photo. The crew weren’t very attentive, somewhat dismissive and forgot my drink and snack, the chair reclined about 3 inches on a 6-hour cross country flight. I was also not informed that there was no lounge available in Newark airport because of renovations, so all around this was one of the worst experiences and I would actively avoid both American and Alaska Air going forward.

Long 5 hour and 45 min flight and only one drink service and cookie snack

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

This flight didn’t happen because AA agents didn’t let us board the flight

We boarded after several delays due to mechanical failure and a gate change. The seat cushion in the exit row was very compressed and offered no cushion, making the four-hour journey reasonably uncomfortable. The WiFi worked for a few people, but for most, it did not, and you cannot get entertainment unless you can connect—American Airlines flights do not have seatback screens, and you must use your mobile phone.

Nothing really nondescript, the flight attendants were friendly and helpful.

Whole experience was poor. Delayed 2 hours. Lied about the delays. Was all jet blues fault and tried to blame on air traffic control. Sent out other let trips and wouldn't allow people to switch aircraft.

Kayak sucked. You gave me a confirmation number that was not useable by the jet blue system. Nor did you send any check in emails. I’ll not be using your site again. Nice work.

Excellent price. Everything on time. two bad parts. Kayak said I couldn't sign in for the flight online, but I got an email at the same time from Jet Blue and they let me sign in online. Second bad part was that, although I had provided my known traveler number, neither of my boarding passes, for this flight and the previous one, had TSA pre-check showing.

Flight emergency landed in Chicago due to “Odor” in back of plane . Had to buy ANOTHER TICKET to get to Boston cash out of my own pocket . Then they would notchange my return flight time without a 400. Charge!!!! Insulting.

we were an hour delayed after boarding and given no reason. Headsets cost money. Also there were openrows with no one setting in them but we were told we were not allowed to swtich.

Crew were fantastic and so catering and wonderful! Full score for the entire crew!

Very pleasant flight attendants. Gate crew rather loud chatting with each other.

Communication with the customer and stay is important. Staff off with a minor inconvenience but it worked out of course. Also this was a very old Mint Class plane. They snuck this one in on us. The updated aircraft are much better.

In-flight staff was very helpful and excellent. However, the flight was delayed by 90 minutes. Also the boarding process should be expedited in case of delayed flights. This will help the passengers trying to make international connections.

Service for food to our seat was a bit slow. Snack choices were just pretzels or baked chips. My seat cushion was not attached. Other than Barbie, video choice were not very good or current.
