Dreamliner is an excellent aircraft. Great seats in business. Flight attendant Alex had a bored, sullen attitude in serving customers. Difficult to get his attention and very slow to respond to a simple request for water. Spoiled the experience a bit as the AA motto is “we’re here because of you”. Attitude needs some adjustment!

There was a certain guy in American Airlines his name is AAROON who tried to charged me for 246 dollars so I can fly from Dallas to DJT Palm Beach International Airport ; wherein it is not my fault why the flight is delayed so why do I need to pay ? I insisted my rights and told me to contact the company who booked me. But upon taking to Japan Airlines people they said upon checking I don’t have to pay additionally. So please check your people who does so things like this to passengers.

The best part was the staff. They are kind and gracious and made it a good flight.

Reasonable price, great service, highly recommended. i arrived well rested!

Since I traveled on my birthday, they gave me a gift and a card. How thoughtful and caring.

Excellent overall, the staffs and amenities were delightful even using the outdated aircraft.

American Airlines didn’t allow you to complete online check-in unless you paid for your seats. Quite disappointing.

Food as always. PA was not clear, especially the English ones. Very limited Hollywood movies. Unlike the first flight I had, this plane has less leg room and less room for my under seat baggage.

Please change menu every now & then bc I fly twice within the year and serving the food the same

1 hour late for unknown reasons. Passengers were not told why. We sat in the plane, I felt the 7 hour flight turned into an 8 hour flight.

On time, food was great. Didn’t wake me up when they saw me sleeping and as soon as I used the toilet, they came up and asked me if I wanted dinner. Right on!

I was expecting to fly in a Japanese airline because that what I bought, very disappointed finding out the change of airline without any explanation.

Excellent. There were setbacks, but it had nothing to do with the crew. Mostly, mechanical which delayed our flight.

The flights with ANA were great. The flights with United, not so much.

It was so disappointed trip by unexpected company's fault delay. It had taken 3 hours delay for mechanical maintenance plus another 3 hours for bad weather.

One of the business class panels where we were sitting was broken and it didn’t close. Therefore, the be privacy was limited.

SEA HND sector internet only worked for the last 2.5hrs of flight….. never had this kind of incident with other airlines

Service is great. Seat is ok. Not much storage room and seat is hard but seat topper was nice. Cabin was very warm most of the flight. Washoku Food was good.

I couldn’t sit with my daughter. we are separate and both seat was not window or halway side. in the middle. if we sit together will be share comfort seat and more easy travel. this is bad.

As my first experience in business class it was a great trip considering how long the flight is and how hard it usually is to sleep in economy

I didn't use the onboard amenities, so it is difficult to comment on those services. Otherwise, the flight from Nashville to Toronto was quite crowded, but the boarding process and the flight itself were perfectly fine.

I Love Delta but one of the flight crew training in courtesy snd hospitality.

The temperature on the flight was unbearably hot and they were unable to serve waters and did t make any adjustments. This impacted us both when leaving, we pushed away from the gate but didn’t taxi for takeoff for awhile then arrived ‘early’ yet were stuck in the plane for longer than we should have been.

My seats are comfortable because I choose to fly in the exit rows and this time upgraded to first class with minimum sky miles. Otherwise, I would not be happy in regular seats or even middle comfort seats. Onboarding on the return flight from Nashville to Atlanta was hot and very uncomfortable for over 30 minutes due to extreme hot weather. However, Delta should provide some other air flow option as it was almost unbearable until 10 minutes after take-off. First class seats should be equipped with cup holders. Currently, the middle console is used and is flat and prone to spilling drinks.

There is consistently no communication/updated time slots in the app on when a flight will board when its delayed, which is the most frustrating as a consumer trying to understand if they need to get food now, or if there is actually a chance for them to eat during their layover. This keeps being my experience with delta and a potential reason to change airlines.

My flight home from Knoxville, TN, included a layover in Atlanta. I boarded the aircraft in Zone 5 and although there was limited overhead space, I was able to put my 'backpack' style roller-bag above my seat. Unfortunately, due to continued bad weather, we had to deplane. There were many people who would have missed their connection, so they rebooked. When we were re-boarding, the gate agent welcomed zone 5 and then made an announcement: All roller-bags for zone 5 passengers and higher will need to be gate checked. I promptly pushed the telescoping handle in and held my bag like a backpack. I was able to bring it on board, which was a relief. Upon entering the aircraft it became apparent that there was easily 40% open overhead space. There were audible signs of angry passengers who felt duped into checking their bags when in fact there were noticeably LESS passengers on the aircraft and TONS of overhead space. I'm not sure what kinds of parameters are used to determine when to cut off roller-bags from being brought on board, but it seemed deceptive and underhanded to have so many people get stuck checking their bags when clearly there was ample room for at least one more zone.

The CRJ-900 was clean but the overhead air vents were broken in our First Class row, making the cabin very hot until about 30 mins into the flight. The flight attendants were both extremely apologetic and accommodating though so that is why I rated the flight as very good. They checked on us many times and truly showed they cared. The snacks for an hour and a half flight could be better. Would be nice if there was a small plated meal over convenient store snacks. WiFi also was not working. And it would be nice if Delta had adjustable headrests on these planes.

I was in Comfort and we didn’t get any drinks, chips or anything! First Class got full service on the flight and Comfort got nothing. Seat was horrible and uncomfortable

Short trip, no food and therefore no expectation for much interaction with staff who were pleasant and professional. My critique is on comfort of the seats. Exit rows and comfort seats do not provide enough personal space for 3 side-by-side seats, especially when in the middle row. Some passengers are not considerate of the middle seat and there should be signs that state something to the effect of: "please consider giving middle seats use of the armrests."

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

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.

Weather delayed arriving flight and even though I made the connection, my luggage did not.

The service was better on this flight from the long haul one, but still very poor from The Cathay Pacific of the past.

Seat was very old. Didn’t easily go up and down. Flight Attendent had issues moving the seat. Condition of the seat was ok. Parts were peeling off by the foot area. Food was ok. Ran out of the dish I wanted so got the beef. Beef filet was very tender but the sauce was a little strange. Disembarking was very easy.

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.

Baggage delayed for 2 days and still chasing for reimbursement of basis items. Very horrible customer care service.

Crew experience was more transnational, seats were so close together (LtoR and FtoB) that it was difficult to enjoy much of anything. When the person in front leaned back, there is no space for me. Sadly it was a flight to be endured not experienced.

One of the worst flight in business class by qatar airways and I’m no stranger with qatar airways businesses class, I travelled with the extensively in the past 12 years

Everything was good food could be better but ok for economy on my 2nd flight the head ph jack are bad you have to hold pushed in to hear anything but other then that very nice service

My easiest trip ever. Flights left on time, and came in a few minutes early. The flights weren’t full so it was very comfortable. Thank you United

The united employees at the gate treated me very rudely and called me nefarious

The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

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

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

The internet service I paid for didn’t work at all and the flight crew was not very friendly.
