Airline reviews

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.

While they turned off most cabin lights to allow people to sleep, I was bothered by how bright the side lights still were. It was still quite bright for me in a window seat, when I wish I could have slept!

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.

The crew bent over backwards to thank us for flying and make us comfortable. The food service was quick and efficient. The Captain communicated and said goodbye and thank you as we departed. They really stood out!

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

Staff at the check-in counter were friendly, happy and helpful. They tagged our bags and sent us to “bag drop off” but were not very clear about where that was. The airport was busy we headed off in what we thought was the right direction until a gentleman waved us down and actually came after us. He was the baggage handler for Delta and recognized our “deer in the headlights “ look-he brought us to the right area (which was marked as the Southwest Airlines Drop Off) and sent us on our way. Wonderful guy, low key and working with a big smile on his face. Loved it. Loved him.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

I haven’t flown economy in over 20 years but it was not bad. Room by my feet for my bag and seat was roomy enough. Surprised in a good way.

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.

Checking in united could not figure out my star alliance gold. Baggage did not get marked priority and didn't receive boarding passes. When got to SFO lounge personal fixed everything Immediately

Flight left on time, arrived early, pleasant staff provided water, coffee, etc. access to bathrooms was reasonable and were well maintained. blankets were available, lots of entertainment options. LUGGAGE SERVICE WAS GREAT. I got my one checked bag quickly and was able to make a bus connection for a 2 hour bus ride saving me from waiting another 1.5 hours.

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

Horrible service no Wi-Fi connection on both leg of the flight and they are refusing to fix bad service

I will never fly ANA again. They lost one of my large pieces of checked luggage, the heaviest one with the most valuable items in it, and they said they will not send me an email unless they can't find it, even though the paper they gave me to track the status of my lost luggage requires a code from an email they are supposed to send me so I can do baggage tracing. They claim to be an international airline, but they also insist on calling a Japanese telephone number to confirm where to send the lost baggage if they find it. It is impossible to find an actual contact email address for customer support on their website, and their AI chatbot is unhelpful, directing you to a webpage that says it is for contact information but does not have any actual email addresses or phone numbers listed on it. My seat in economy did not recline at all, even though I was not sitting in an exit row nor the very back row. I had to sit in the fully upright position for over ten hours of international travel. Awful experience overall.

Overall we had a good experience during our flight from San Francisco to Houston.

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

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

To have arrived on time and not 3 hours late after having already spent $100 to change to an earlier flight, only to arrive back home close to the original flight time.

American Airlines is a miserable experience. It is predictably miserable, in the sense that every time I fly American, I brace myself for the certainty that it will be unpleasant and uncomfortable. But it is unpredictable in the sense that I never know if the flight will be on time or delayed nine hours (both happened to me this week). I never know if I will be able to sit in the seat that I selected when I purchased the ticket or if I will be told by Customer Service (!!!) that I must relocate from first class to a seat in the back of the aircraft with no explanation (both happened to me this week). Will the food be frozen and half defrosted, or scalding hot? Will the drinks be warm? Will the flight attendants be surly and mean? Will the toilets be cramped and foul? Will the seats be narrow and uncomfortable? Will there be a real electric outlet at the seat, or just an unreliable USB-2 port? Will there be enough seats in the boarding lounge or just a few? Will the boarding process be smooth and efficient, or will the gate agents mess it up and delay it needlessly for 30 or 40 minutes? Will the catering and cleaning crew be prompt or will they take an extra 30 minutes? Will the brakes on the aircraft work properly, or will the pilot delay takeoff for four hours while the ground crew attends to what can only be described as routine maintenance that should have been done the night before? I've eexperienced every one of these unpleasant things this year, 2026. The only thing I can reliably count on is that American will find a new way to make the experience of flying as miserable as they possibly can.

Wifi was spotty. Tray table was very dirty when I sat down.

The WiFi would not connect enough for me to do my actual work. It permaspooled, disconnected, said it was connected, then wouldn't open an email... it was frustrating. I am not a tall person, 5'4" - and I felt cramped with little room to reach into my bag under the seat in front of me. I feel sorry for anyone taller than me having to fly. the one positive thing I will add, is the overhead bins are roomy enough to manage more bags than other carriers.

Buying ticket from kayak instant booking was a huge mistake, never to be repeated again! The Kayak didn’t book the tickets directly, it handed it off to a third party Underpricer, that booked a code shared American Airlines flight operated by Cathay Pacific!! When managing the booking American Airlines would recognize the itinerary but wouldn’t let me do anything stating, the flight is operated by Cathay Pacific so go to their website. Cathay Pacific would recognize the itinerary, neither by reservation ID or ticket number…asking to reach out to the third party Underpricer….calling Underpricer resulted in no help like seat requests, mileage number or upgrade request, 15hr layover accommodation voucher guidance…so net in net avoid booking through three layers of intermediaries

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

Delayed for mechanical and no updates on what was happening and how long the delay might be.

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.

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.

My experience with JetBlue was fine BUT I am very upset with Kayak! JetBlue had delayed our scheduled departure by an hour and you NEVER notified me of the change. I did not hear directly from JetBlue because the trip was booked through Kayak, a mistake I will not repeat. Your reminder of the our trip last week still had the WRONG departure time. Our return trip has also changed, and again no notice from you.

Not having an assigned seat until boarding and then having to check my bag.

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.

I purchased ticket so our daughter ( a minor) can sit next to her mother. No help at gate after kayak insisted that this could be done. She ended sitting by herself

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.

Terrible. There was a lot of misleading information regarding ticketing, seat upgrades, & boarding group. I also expect my seat will recline. I have back problems & it is very painful for me of the seat doesn’t recline. In addition, when I choose a fare that allows me a carry-on bag, I expect to be able to carry it on. Not be forced to check it. Thos happened on my flight to MCO & back to Boston. Not sure I will ever fly JetBlue again. Further I bought the ticket through hat deal. I will NEVER do that again. They were incapable of providing an accurate record locator # for either leg of the trip. I had to call them before each flight with me VERY stressed about whether I would actually be able to get on my flight. Who does that? Who books flight & then FAILS to give an accurate record locator? Twice!

The flight was delayed 4 hours and the JetBlue people at the counter kept lying to us and telling us it was due to weather however all other flights were going in and out of NY and FL. Then they lied that the plane had to stop to refuel. Then they lied and said the plane needed a tire change. JetBlue is the worst. Then they gave a lot of people meal vouchers however I didn’t know they did that and they didn’t offer anything to me.

Jet Blue has excellent everything, Friendly customer service and staff, clean aircraft’s and is always on time.

I was traveling with two small kids and our TV s were the only ones not working. Informed the flight attendant who did nothing about them.

It was an early flight and most people napped/slept and the crew let us which was nice.

Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.

It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option

This company socks. It's fraud. They canceled our flight yesterday, and today we were late because of a really long line at the check in bag. At the rebook station, there was ton of people. The workers were all rude. I am gonna make a report to FTC.

Flight got delayed for 5 hours no good explanation was offered ;(

There was no one at the counter to assist with our check in. The app didn’t work, so I arrived at the airport with time to check in and I couldn’t because no employees were there. When I finally got someone on the phone, it was inside the 60min rule and they said I could no longer check in and they could sell me another ticket. We had to scramble and pay an additional $800 for tickets and THEN AFTER (about 60 min from my original convo with customer service and 10min after original departure time) I had boarded my new flight, there was email saying my original flight from Frontier was delayed and leaving 2hr 50min later, but I STILL wouldn’t have been able to check in. Which means customer service should have been able to see it and let me check in because I was well within my check in time. When I call Frontier, they hang up on me. So their app didn’t work and they employees left and they take zero responsibility or assistance with their “customer service”

Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.

i was unable to check in the flight. refund requested

Everyone seemed to be in zone 1 for boarding. Maybe break it up a little. Otherwise, smooth flight.

I think Frontier was very good at communication. Their app worked very well. Loading was great and the flight was nice and easy.
