Airline reviews

The original email I received and flight that I paid for was for Japan Airlines. Since JAL is a partner with American, I ended up on an American Airlines plane. This would not be a problem, except that JAL allows 2 check in bags for free and American only allows 1. A $100.00 unexpected expense was very disturbing, especially since I will have to pay it again on my way home. I feel like it was a bait and switch. I never would have chosen American Airlines if I had known that I would have to pay $200.00 in baggage fees, above and beyond my airfare. Secondly, the check in counter representative did not realize that I had TSA pre-check, so I had to return to the check-in desk on a different floor to get a new boarding pass. The AA representative helping at the check-in kiosks was very helpful, kind, polite, and professional when I returned for the new boarding pass. Thirdly, the crew was not as friendly as I have experienced on other airlines. Their tone when speaking to other passengers was not always polite. The food was better than I expected. However, I am used to having a station where one can serve themselves water, juice or grab a snack. That was not the case on this flight. Truly makes me think twice about booking with American Airlines. I am very disappointed.

Crews are rude and short. Example: after my drink and was ready to prep my bed to rest. I tried to give my empty glasses to the steward while she was playing her card game on her iPad. The steward told me to take the glass back to my table instead of taking the glass out of my hand. Compare Japanese steward it’s like heaven and hell.

The seat was uncomfortable and seemed to be on its last days. Loose and sloppy

I traveled business class from Lax to Narita flight Jl61. The crew was attentive and polite. Food was good quality and service was as it should be. Narita to Bengaluru Jl753was another story in business class. The cabin was darkened for the 9hr:30min flight, food was mediocre, service was below standard and crew can't speak English to save their lives. When you ask for noodles soup from Ala carte they gave cup of noodles while Lax to Narita i was served the best Ramen noodles in a big bowl. Why the disparity on this leg of the journey.....or is it because there were mostly Indian passengers and it really did not matter to Jal to bother as its a poor country and Indians refrain from speaking up? A good airline but differentiation like this brings their reputation and business down.

put me in front row, screen was tiny, movie slection wasnt very good will be flying back on another airlines

Japan Airlines was excellent as usual once on the plane. Cabin crew was wonderful as usual. Boarding was solid on the Honolulu leg. For Thai Airways the boarding was less organized. I was in an earlier group but they weren’t clear with the numbers or instructions. Flight crew from Japan to Thailand was very good.

Terrible. Our flight was delayed by 15 hours. We lost a full day of our vacation.

Not good. The flight from LAX to Tokyo was delayed 15 hours.

highly recommend for trip to japan only reason why i gave good not excellent is because their selection of movies and tv shows in English is more limited .

I avoid American Airlines for a reason. Our flight was delayed at LAX. The situation at the gate was chaotic. The woman making announcements wasn't being clear or transparent regarding why there were delays. There was a lot of confusion regarding flight and gate status. Other passengers were pretty rude. I was elbowed in the eye by someone who was in a hurry to get their bags from the overhead bin immediately after the flight landed. Ultimately, I will avoid AA as much as possible in the future.

The staff were so friendly and accommodating. The food was great. Lots of movies to choose from as well as tv shows. Highly recommend.

Leg room wasn't that great. Other than that it was a good flight

Issues: 1) the charging issue as described in my previous survey 2) when I requested diet coke during the breakfast time, it is not available. Why? I can't drink diet coke in the morning? 3) when I tried to transfer to this flight, its gate information was not available to me?

Chicken pieces were too big with pasta. Need to be smaller.

Seats in the absolute back row of the plane even though we booked ages ago :( Crew was awesome though

My connecting flight was canceled or never existed. My stopover went from 1 hour and a half to 10 hours. It was a long day that I wasn't prepared for and it would have been nice to know that ahead of time. Cathay is great though. Great staff, entertainment and food.

I was only given 2 meals, and my screen showed that there were 3 meals. Second meal was 1-2 hours late according to the screen.

Paid a premium a have a shorter transit time in Hong Kong, but Cathay pacific rebooked me and ended up waiting for 10 hrs in Hong Hong airport.

Entertainment for kids was good. Good was terrible, needs lots of work.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I was travelling 3.5 years after. Agree Economy is no business class but the food was mediocre. Ordered a Hindu meal, the salads were bitter . The food was really below quality and had no tast from what I had in the past. Indian Railways probably have a better quality food when compared. However the kids meal was really nice and really appreciate how they were taken care of. The restrooms were dirty .

My flight was with American Airlines 120. The flight was delayed 3 hours and I missed my connection. When I arrived in Doha, the AA staff told me to call an 800 number to rebook a different flight, which was unacceptable. Eventually a Qatar Air staff member helped rebook me on a flight to Manila, that was 12 hours later. They offered me a hotel and meal voucher which I declined, because I didn’t want to leave the airport. Long story short, I spent 12 hours in the Doha airport waiting for my next flight.

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

Reason for travelling Tampa to Orlando is to fly Qatar Airline. we end up with American Airline. This was the miserable experience I ever had in my entire travel history. Flight attendants were rude. They hit my knee with the food cart and I was holding ice pack for 2 hours. I still have the pain after a week. WE boarded the flight twice because of the temperature inside the plan.

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

Even though we were delayed, we were able to make our connection

Seats in waiting area and on plane hard as rock. Fast internet on the flight was great! Crew was kind.

Starlink wifi on the Embraer E175 is an excellent experience. I was able to connect and work from IAD all the way to approach into BTV.

Older aircraft, no meal, only food was for purchase. Not impressed United.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Always wish for more healthy, gluten free options. We have to bring our own.

Having a long layover, I was very appreciative of the ability to stand by for an earlier flight. Other airlines like Delta have refused this to me in the past, just to be mean (because my ticket class wasn't high enough). United went out of their way to help me get to my destination early, which I really appreciated given that it was the third leg of a 24+ hour journey for me.

Other than a way way too cold cabinets for the entire flight, all was great

One bag is incorrect and not acceptable for an international flight. The food was not just good. I won't fly with them again.

Not pleasant trip cross country when the entertainment and WiFi system not working. No entertainment for entirety of route. Staff was rather nonchalant in that they dismissed the problem due to age of plane. It would have been nice to know this up front so I could have come prepared to read or download movies before boarding Coincidentally or not, there was a similar issue with the entertainment system on my previous flight I took on my fist leg of the trip. There are no seat TVs, so you must rely on the app when it works. United can do better. Also, what use it it to pay for boarding group 2 when half of the passengers are in the same line as you?

More choices on snacks. Built-in video screen to enjoy entertainment choices.

we landed at cmh ten minutes early but had to sit on tarmac for twenty minutes because a plane was at our gate despite the fact that 3 other gates were open.

The experience with American Airlines was good, although the Philippines Airlines flight was much better (better seats, better food, better entertainment options, overall better). Again, the MIA to LAX flight was fine, but nothing in comparison to the comfort and accommodations of the Philippines Airlines flight from LAX to MNL.

I have a gluten allergy so did have any food

I have a gluten allergy so didn't have any food

Loved the crew . Absolutely no complaints. Except for luggage lost

Everything was good The connects, with no blame to crew. Or pilots. I understand they are short staffed. Everything went well for me. I'll be using you guys again in May if not sooner.

this plane was really old, had exit row seats and tray was in arm of seat so super uncomfortable to use. another seat they could t even use the tray it was broke. seat i. front of me had duct tape on it cause seat was ripped open... this plane should either be updated or retired.

We were very rushed by a staff member at the gate when transferring from American Airlines to Fijian. Then the plane stayed put for ages anyhow! The plane was delayed and my bag sent to San Francisco instead of Fiji

Baggage handling poor. Second time this has happened. My bag went to San Francisco instead of Fiji. No apology. Luckily Nadi airport staff are fantastic. My bag arrived in Fiji the next day.
