Airline reviews

We did not receive our special meal request (vegetarian). The crew was apologetic but then kept interrupting me at least 6 times to ask to see my email or access the web to show verification. (I did not have internet access while on the plane). They kept asking the same questions and taking down the same information. It became exasperating. I understand these errors occur but the constant questioning was disrupted and only compounded the error.

Older 777 - showing lots of wear - Premium econo seats that are difficult to recline and worn springs to they don't return to takeoff position without standing and pulling them forward

Excellent. All the ticket prices have gone up so much. With only economy as the option, I thought I better pay for a good airline and I am glad I took ANA. The only thing is the long layover at Hanaeda enroute to Singapore. Any chance to bring back the service to land at Narita instead for the transit and a shorter layover will be fantastic. I am a fan of ANA.

Good. Got me there and back safely and mostly on time. 30 min delay for maintenance once but that means more time for nap. Crew was super nice.

Incredible. Amazing legroom. Over head fans for each person. Tv screens were great. Headphones were adequate. Seats were comfortable and spacious. Loved it.

I booked a ANA flight, this was just a regular United flight — as always very bad, dirty, rude service, quite frankly really embarrassing to be flying with this after spending time in Japan.

Staff and crew are wonderful, professional and courteous. Meal is delicious and snacks can be improved. Entertainment needs improvement, pls update selections of movies. I appreciate that our flight was on time

I flew economy class so of course it’s not as roomy as business and first class. But overall it was ok and the seat had an interesting way to recline — the seat itself extended forward instead of the backrest. This way the person sitting behind me would not lose space by my reclining—excellent concept. I wish all airlines used these seats.

Flying with ANA is always a breeze. Seats are very comfortable.

For the price of a seat that is obviously crammed together so as to get many more people onboard and combined with the long flight duration, Free WiFi should be an automatic “Thank You for Flying with Us!” To charge an additional fee when so many other businesses offers it is a bit “cheap” on the airline’s part.

All of the JAL flights in this itinerary were great. However the last leg of my flight from LAX to SFO was through Japan Air’s partner, AA which wqsn’t up to par. We were informed only minutes before boarding time of a delay despite the airlines knowing about the delay far earlier (the aircraft we would be taking arriving arrived and disembarked close to our boarding time, for all to see but AA still kept the original boarding time posted until last minute). Furthermore, once we boarded the taxi/wait time was also extended, with the pilot blaming “construction at SFO” for the delay, rather than taking accountability for the the plane’s late arrival coming into LAX. We took off approximately an hour later than scheduled. It’s for these reasons I adamantly avoid American Airlines when possible. Again, JAL was stellar.

Great service but food taste and options have gone down a few notches.

This airlines is always my favorite. Very consistent customer service and food is good. My last flight with them, I had no idea we landed because it was just that smooth of a land.

At least it was not very cold inside the plane. I noticed there was now a bidet in the bathroom and that’s good! I didn’t like the window seat. Flight was smooth except for 1 turbulence. Plane was on time. Thanks. Food was not that great. Miso and green tea were good! As usual movies were old and there were no changes.

The food was not that good. I liked the miso, green tea, and ice cream. I wasn’t able to put my carry on bag under the seat in front of me. The flight was smooth. Please expand your choices of movies especially the new ones. I can’t choose any of those films. They’re old.

I didn’t like the check in process I had to check in at the counter took too much time . Didn’t give the upgrade my seat .

Good and movies are so old. Needs to have more up-to-date movies.

It was one of the best experiences. The staff were amazing. JAL is my second favorite Asian Carrier I have flown on. Korean Air was my first. Thank you JAL for bringing me home safely and for such an amazing staff and service.

JAL is quite nice in business class. Comfortable, spacious seats. Their entertainment, especially their film selection, isn’t that great though as their are not many new releases like some airlines offer their first and business class customers. . Food is excellent and the option to order on demand is always quite nice, which JAL offers. Flight attendants were very friendly and kind. Overall very good experience with JAL.

Very comfortable unlike my first trip where they switched my flight from JAL to AA which was a disaster!

3 hours late and all they have is was a $12 meal voucher. That’s not even enough to cover fast food.

Among the poorest flights I’ve had with Delta in a while. Entertainment system failed completely on a 7.5 hr flight. Crew seemed distracted and not the normal friendly crew. Flight overbooked it seemed… very crowded.

If I can, I always fly Delta. I’ve found their service to always be reliable and pleasant.

You could have not cancelled the flight (AA, which I will be flying from now on) left for BOS despite the fictitious weather issues (that no one in my Boston family could see). You could have rebooked my direct flight to another direct flight instead of sending me though JFK, the worst US airport after O’Hara You could have rebooked me on a Main Cabin seat (like the one I paid for in my original ticket instead of putting me a the last row on JFK->BOS leg, pocketing the difference in ticket price But I do not really care whether you will ever do that in a future because in a future neither I nor anyone from my company (unless they pay out of pocket) nor an of my clients and partners (if they heed my advice) will ever be caught dead on any of Delta flights

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Ongoing flight was delayed. Staff at bag recheck was able to get us on an earlier flight. With only 20 minutes till take off we feared our bags would not make the new earlier flight. We were most delighted that they did and were there when we landed. Delta came through

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Not worth the price of premium class ticket paid, felt more like steerage.

I have to wait for plane in Denver for three hours. I don’t receive my luggage in Denver. I come back home without the luggage and I wait till next day to see my luggage again. Not really good experience with United airlines. I’m sorry to say that.

The Wi-Fi was unavailable on this flight for some reason.

This was a Lufthansa flight, not United. The CSA at the counter, Ashley, was not only incompetent, but quite rude. Me and two other PAX waited over 7 minutes standing in front of her and another CSA and they ignored us. We joked that we must have accidently taken invisibility pills. She could have at least said "I'll be with you in a moment, I'm currently....". I could go on about how rude she and the other CSAs were (whispering, not communicating with me, blaming the situation on others, etc.). She would not work for me. Then, she gave me literally the worst seat on the plane. the worst. My seat kept getting bumped (rammed twice by the crew with their carts and about every 5 minutes by someone using the bathroom), listening to the bathroom all night, crowded seat, etc.

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the room where it was being kept.

T hey did a great job. Flight was on time .

Good with British Airways - terrible with American Airlines! Stood at gate for “mechanical problem” - plane delayed. Had to check my personal belonging with 5 empty bins available in plane, desk staff rude!!! Toilet not working- asked “to use working toilet sparingly - it may overflow in cabin!”

Paid for premium economy had no tv the whole time the crew tried to reset/reboot but would not work they said they would put a trouble ticket in for it. We had 3 seats my tv was the only one that didn't work. They cancelled our flight re worked us on another that left us at airport over night on the floor I have a ten year old and a 78 diabetic mother which also had shingles and suffers from nerve pain in legs and back. Requested wheelchair service at all airports after the re route NO wheelchair service was there to help. WORST experience we have ever had. Went to American airlines assistance it was closed. I AM FURIOUS!!! I expect some sort of compensation from this traumatic experience and no need for flying points we don't plan on using American airlines again!!!!

The flight was sequentially delayed until it reached two hours. Apparently one pilot failed to show up.

This is by far the worst experience I have had with American Airlines. The start of this trip was a complete disaster. I purposely planned my trip so that I would weather any delays so that I could make very important meeting at the Pentagon. My flight was cancelled because of maintenance and I was put on the first flight the next day but I was late to the meeting. After a long week at the Pentagon I just wanted to go home and my flight home which was early in the day was delayed. Eventually the flight was delayed until the next day. I was not authorized a hotel room because DCA was my point of origin. So I paid for a hotel out of pocket. The flight this morning was boarded then deplaned because the aircraft was hot. The flow of information was not happening in DCA and made it worse when the news was bad. I am going to take a break from American for my next few military flights. Hopefully whatever has been going on with American Airlines will be resolved.

We had a 2 hour delay. The seats were smaller than most other airlines. The person in front of us wanted to lay back and we had to stop her because she was pressing against my girlfriend’s legs. We had to ask her to sit up and not lay back due to the lack of room.

Everything was fine once we actually got on our flight. It was more then annoying they canceled (delayed) our flight. We lost out on a day of our trip along with money on our stay. Plus we had to book another hotel. So expensive.

This flight was canceled and delayed several times without explanation. The plane was freezing cold and no wifi for messaging. Getting off the plane was terribly unorganized and felt like it took forever….

The flight was delayed several times without explanation. The seats were terribly uncomfortable and wifi isn’t included. All these make for a less than ideal flight.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

Internet service was erratic. Crew service was poor and slow. My luggage on this non-stop flight was lost and not recovered
