Except for the uncleaned tray, and the delay in serving food for our section (which may have been due to the location of our row) everything else was good. The crew were very professional and responded to our requests promptly throughout the flight. We as a family were not disappointed by Emirates.

Except for the uncleaned tray, and the delay in serving food for our section (which may have been due to the location of our row) everything else was good. The crew were very professional and responded to our requests promptly throughout the flight. We as a family were not disappointed by Emirates.

It was great, a little more leg room would have been better particularly since we were in premium economy

The boarding process was smooth and the stewardesses were nice. Some delays with drinks at the end of the flight, but no issues.

Thay crew was so nice.Air hostess il ham was so nice.my mom was little scray with airplan turbulence she help us alot.

Seat 💺 was all the way on last row. Food was okay .

Charged for internet that never really worked. The food selection was just ok.

Boarding, seats, entertainment and service were all great. Food was great except for the fact that there were too many sweet items.

The entire crew went above and beyond. This was our first flight with our 3 month old, and they were accommodating and friendly. The crew is attentive and marks a HIGE difference to the regular runs with Avianca and LATAM.

Business class on this plane was adequate, service, amenities, swag, and crew was amazing!

Airline did not have enough vegetarian meals for all guests, and crew were not adequately trained to handle this.

Well organized boarding, efficient and on time. Nice crew on the plane. Thank you!

The Qatar Airways staff pre-boarding and also on the flight from Dallas to Doha were incredibly mediocre and arrogant. Consider retraining these individuals Other flights were ok.

My experience with Qatar airway was very unsatisfactory. They lost my child’s stroller and I was told they found it and will send it to the hotel which was a lie. I had to go back to the airport baggage claim and pick up myself after trying to contact them many times!. There was a lack professional and communication. I am very disappointed in Qatar airway and will not be recommending them to friends and family nor will I be flying with them in the future.

Worst air experience in whole life . Boarding and checking was hassle as they did 3 times. Crew team was clueless about passengers need. Despite of passengers raising hand , they were resetting the program

The food is not good and also if you ask crew to bring something they say ok I will bring but you will never get it. Please they should listen good to passengers

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

Did not like anything. Seats were crammed, leg space was minimal and food was terrible. This was the first time traveling overseas in American Airlines and was the worst experience ever. Have learned a lesson to never travel in American Airlines.

Delayed my flights and no communication. We end up spending 6 hrs in Doha. No food or any concern from the airline. Terrible

Check in desk people constrained by fear. Obvious typo on Uganda visa, even though approved, caused loss of flight. Something is definitely wrong with this system.

Between Air India and Qatar my luggage was lost for three days. I eventually found my own luggage location using the Apple Air Tag. Air India used a paper form to report my lost luggage. I could never get past getting past luggage personnel with my report number before they would hang up on me. Only after them specifically telling Air India at Chandigarh airport where my luggage was located which was right under their noses did they react. After three days I finally received my luggage. The Air India luggage folks didn’t seem proactive in finding the luggage’s rightful owner.

Extremely bad food, they never gave our bags in time, the online check-in did not let us check in because we had Indian OCI not sure why we were given the option to check in then, because we couldn’t check in online we had to go in person and we were not able to change our seats and sit with our family

Should have had business class line in immigration. Food quality suboptimal

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

The staff were wonderful but the seats weren't very comfortable for a bigger guy like me.

Bad. Flight was very uncomfortable with narrow and shallow seats, very little food and water. I will not fly etihad again.

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

Good. The food was very bad. Except for the chicken rice, rest of the dish went to trash.

The flight was delayed which cause me to miss my connecting flight in AbuDhsbi airport.

Only 1 time food and drinks together was offered, for total 5 hours duration drinks and snacks was never offered. For some people food choice was not available, only veg was available. No entertainment option was there. Crew members were mostly back of the flight asking each other for KitKat and chips to share between them.

Etihad flight sector is a local . .give the same quality upto destination

Cleanliness of seats, trays, storage pockets need more attention, but everything else was good.

A great airline, no complaints at all. My experience with Cheap Tickets was very disappointing however. Two hours after purchasing the flight they called to tell me that the ticket price had gone up. I’ve never heard of such a thing. That is called false advertising; I will never use this ticketing service again and will warn all friends to never use it.

One of the worst check in process at the DIA as well as the boarding counter Changed seat at the last minute and assigned middle seat while I paid for window seat. Requested many times but to no avail . horrible customer service and very poor process Requesting refund for seat that was changed last minute

Good overall flight. Excellent crew. Food options could be improved.

Vegan food tasted good. Restroom could be kept cleaner. Seat tray table was a bit tilted so food tray kept sliding down a bit. Flight crew can be a little more friendly, caring and approachable. Their faces lacked smiles and tone was stern.

Flight was delayed then we had to redirect for medical emergency during which time we had no information on what is the plan. The connecting flight was also delayed.

Professional & courteous cabin crew. Food was very good even in economy class

7 stars hospitality and an excellent service by the Turkish Airline entire team. Somehow, our membership numbers for mileage points were not indicated on our boarding passes issued at O’Hare Airport by the Turkish Airlines check in desk. During transit in Istanbul, I brought to attention of customer service Turkish Airlines. Please have our mileage points posted to our membership account from O’Hare Chicago to Lahore for both my wife Kaukab Shirazi Thank you

Terrible boarding experience, with an incomprehensible assignment of priorities. “Fast track” was the slowest. Poor system planning.

Terrible boarding process, no proper line maintained even for business class, crews are not very attentive, business class food quality / variety / quantity have gone down, everything has become cheap.

The boarding experience was good; $20 for wifi per flight is uncompetitive compared to Delta, Southwest, and others, and puts American lower on my list given similar pricing.

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

Delays on all NY flights. There was no communication on why but they didn’t say it was weather. Other carriers were not delayed.

The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

Same as before being upgraded to business class made it perfect

I flew out of Reagan National. My flight was delayed, delayed, delayed, and then canceled ...THREE TIMES over TWO DAYS. Staff were seemingly not empowered to provide information on why the flights were screwed up. A real nightmare.

They cancelled our flight without warning OR a refund. Never doing business with American Airlines again! This is the second AA booked trip in a row that we've had challenges with.

Crew was late. Baggage was late. 2hs inside the plane waiting fro de-icing and traffic. A 3:30hs flight ended up being almost 6hs inside the airplane.

Flight delayed on both ends - have a gate ready at DCA, don't make us sit for 30min after being late to take off as well.
