Airline reviews

Great to have economy + on JAL. Economy + has their own designated check in. You are also able to use their lounge which is very relaxing. There is food, desserts and drinks available as well. The seats on the plane don’t recline very much and the isle way is narrow when you need to use the restroom. The food was just ok, typical airplane food taste. The stewardesses were very nice and helpful. Two meals were provided, and the last meal was a fish sandwich. Too bad I don’t eat seafood. The smell of fish was not a welcoming odor in a confined airplane. Overall, I would recommend JAL, (LAX to Tokyo)

Fine. I like the attendant hospitality from Tokyo to Seattle bettet

They moved my seat without my consent and they won’t refund the money I spent on it. I paid for a front row aisle seat and they moved me to a center seat in the last row of premium economy. They were very rude about everything and nothing like Singapore Airlines or Korean Airways which I flown before.

My experience with KAYAK was an absolute nightmare!!! I will never use your stinking company again, and I have been spreading the word. You stole over $1,000 from me. For the rest of my life, I will always steer people away from your dirty company.

Communication about delays was not very good. Crew and staff were excellent!

If they can provide a direct luggage transit line at JFK airport for all connecting flights, that would be prefect,

SAN-NRT was excellent experience with crew helping and assisting in all aspects of comfort. But NRT-BAN was not that comfortable with no blankets and pillows provided and treating it more like premier economy class. This has been the pattern I have observed where JAL uses non-trained crew, uncomfortable seats, restrooms not working, locking up window seats, business class comforts taken away on NRT-BAN route. Overall quality of service goes downhill on NRT-BAN flight. Not sure why?

I had a hard time checking in as my first and middle names lacked a space. The vendor spent a long time fixing it with the JAL. This should not have been a problem. Check in at ohare was good as Regina was very helpful and kind.

I booked with a traveling agency 1 year in advance. The company then changed our flights trying to shorten our stay months out from our departure that would cause us to significantly change our itinerary especially as a part of a larger group who had already purchased events for the trip. Not only will I never use KAYAK or ARANGANT again, I will never fly with American Airlines again. They did their utmost to ruin our first flight to Japan by turning every flight into an arduous ordeal. The flight home took 48 hours riddled with extended delays and multiple layovers. If you want to to ruin your trip use these companies that take your money and then choose the most inconvenient flights so that they can keep the profits for themselves. Worst experience is ever. Just book the flights yourself. The “savings” are not worth the headaches. Just delete the app altogether.

The best way to travel a long intercontinental flight. Staff are kind, polite and welcoming. Passengers experience a comfortable low stress environment, Customers feel they are well cared for by a highly trained and professional staff. I will shout from the rooftops when I get back home, "Japan Air is the way to go!"

We experienced delays in small increments that added up to more than an hour. At the gate, staff showed little concern and compared our delay with the inbound flight’s two-hour tarmac wait, which didn’t address our situation. Once onboard, the flight attendants seemed tired and unfriendly. I understand delays are frustrating for everyone, but passengers shouldn’t feel blamed for them. During the flight, a bright light above the emergency exit stayed on. It was concerning, and no one explained it or offered passengers the option to move. After landing, we waited about 30 minutes on the tarmac for a gate, then waited again for an agent to connect the plane to the terminal. From the Reagan gate staff to the cabin crew and RDU personnel, the service felt dismissive throughout. Overall, this was a stressful trip and a very disappointing customer-service experience

delayed take-off, then had to circle in air for awhile, wi-fi did not work, then the cabin got extremely hot multiple times and the luggage was at wrong carousel at LGA. In addition, plenty of overhead space so they checked bags too early. Horrible flight.

WiFi only works on about 75% of my Delta flights. I rarely fly SW, but their WiFi works 100% of the time and is easy to connect. On my DL flight from DCA to BNA today, I try to connect to WiFi for about 30 minutes, but I gave up. I have a lot of work to do, and I lost two hours today. Very frustrating.

Flight was delayed for about an hour but overall good experience

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

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.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

715PM departure was 2.5 hours late. Received hotel & food voucher but after we already booked a room. Entire team just seemed like they were 2-3 steps behind in execution, and notifcations.

Great flight. I should have figured out the bed situation in biz class earlier. Confusing in dark. My bad.

Business class check-in was flawless; was automatically given a lounge voucher. Flight attendants were helpful and professional. There was a purser who introduced herself at the beginning of the flight but then I never saw her again.

For a 17hr economy flight it wasn’t bad at all, thankfully it wasn’t a narrow body plane.

Simplicity of boarding and corporate interactions were all totally positive and simple, brief, organized and clear. No regrets at all. I will favor flights with Cathay Pacific in the future.

Big selection and great food and beverages in business class with good service. Full recline but less privacy compared with Qatar.

Really impressed with the Airline and much with the Crew. The crew was amazingggg, changed seats very easily, provided a lot of snacks on demand, the plane is nice and clean, the menu is well presented; unfortunately, the food is not fantastic, but it's not bad either but nothing to rave about. I am still rating it as excellent because I loved everything else; food improvement will be great!

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.

The plane was dirty, the seats were torn and broken, the service was the most terrible ever, the bathroom dirty, they will not even serve water you had to request it, the meals were terrible, overall less than Zero, I will never fly Cathay Pacific again.

Despite the crew's rough day, they were all very focused and friendly. The flight was too short for a meal, so no rating on that. Re. the AA app. It still isn't ready for prime time. AA works with Cathy Pacific for international flights to LA and the Aa jump to PHX. But the AA app can't find my trip and this can be problematic with flight delays and regatings at LAX.

Was not able to board flight because boarding pass name did not match passport name and no one caught it.

Flight was on time, and was nice and easy.😁😁😁😁😁😁😁. Arrived on time all in all a great flight.

The flight was comfortable, the food was good, and the staff were excellent. Overall a good flight.

Great experience in business class. Plane seat configuration is dated with three seats in a row but very spacious and lie flat worked fine. Entertainment options are limited but sufficient for the flight duration. WiFi does not work. Flight attendants are awesome and food is OK.

Flight went very well. Cabin crew were all courteous and very helpful, always with smiles on their faces. Food was great. I always love heated nuts with wine. Flying business class with Philippine Airlines is always a pleasant experience.

Great food selection in lounge. Excellent bartender, friendly staff. Good service on the plane.

Check in process was excellent. Lounge needs improvement. Food not palatable and no good choices.

It was never explained why the departure flight was canceled and delayed for 1.5 hours. It would have been nice to stick with the original itinerary.

Many movies do not have captions, which would have been helpful when you have to live with the flight engine noise.

Everything was fantastic!!!! I can’t wait to fly home 😃!!!!!

Flight was delayed and caused us to miss our connection. American Airlines did nothing to compensate us and they lost 2 out of 4 of our checked baggage. They have not returned inquiries into customer service and have not offered us compensation. Terrible.

I appreciate how quickly and kindly the people at the gate at DCA accommodated several of us who wanted to switch from the 6pm flight to the 5pm flight at the last minute. The flight crew was helpful to us too (dealing with luggage).

The couple in front of me were constantly talking over the announcement from the captain and this was annoying me.

Flight attendant incredibly rude. Stuck her finger in my drink and didn’t even have the courtesy to apologize.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

After arriving in Chicago, we were taxiing for 1.5 hours with infrequent and untruthful updates about the amount of time it would take to arrive at the gate. Minimally, the team could have provided timing expectations that were more truthful, especially one their original expectations were not met.

Wonderful. Quick boarding. Early departure and we arrived 30 minutes early at our destination. Unfortunately, when you arrive early, there is still a departing aircraft at our gate. We had to park for 30 minutes until the gate was clear. So our early arrival was not really early at the gate. Otherwise it was a quick and smooth flight. Appreciated the efficiency.

Never nice, United Express partners always do an amazing job.

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

The flight was on time and the crew were great.

I was forced to gate check my carry on luggage. Somehow it did not arrive at my destination. I still have yet to receive my bag r days after arrival.
