Both the staff at check-in counter and on board were pleasant and helpful. My chicken and mashed potato was good, sauce was tasty, but the zucchini, carrot n other accompanying vegetables were over-cooked a little. (I understand the meal has to be prepared earlier). Yet I would fly on Singapore Airlines again and recommend it to family and friends.

Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

Everything was great keep up the good work 😁, can't ask for more.

Flight from SFO did not include entertainment as it was not working the entire duration of the flight. Was informed that there would be a $350 voucher for the inconvenience. Uncertain how the voucher will be provided.

It was an average flight. I would have expected more from this airline. Food, seats, service, etc was just average. I just give them some extra points for offering free WiFi on board with just a Krisflyer account.

The food options and quality could use some more excitement and variety.

Overall, very good. The food was better than expected with the exception of the pork and potatoes dinner at the end of the flight. My family all selected that dish and did not set it. I tried a bite also and it was honestly terrible. Also, it would be helpful to know when the snacks in the back of the plane are available.

Everything was good except food , food choices was very less. Washrooms were closed.overall good experience.

This trip was the most comfortable one I have ever experienced, the team was excellent and very helpful. I am so glad I picked Qatar Airways.

All the crew members were too slow and rude. Most of the times the registers were empty, while hundreds of customers were waiting in line, and it was impossible to get a supervisor. Despite being in line on time, I missed my freight, plus a some customers who were ahead and behind me.

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

second leg was more comfortable. Customer service in Abu Dhabi is okay.

Certainly! Here’s a more concise and refined version of your report, maintaining a polished and professional tone: --- Crew Check-In – Kolkata (CCU) The crew handling check-in in Kolkata was outstanding—efficient, courteous, and highly organized. Flight Segment – CCU to Abu Dhabi (AUH) A standard flight overall. Notably, only one in-flight meal option—a vegetarian curry—was available, which seemed unsuitable for a red-eye journey. The crew offered no alternatives, which was unexpected. Flight Segment – Abu Dhabi to Rome (AUH-FCO) Comfort improved on this leg, but service quality was average, falling short of Etihad’s premium standards. Crew attention was heavily absorbed by a difficult couple in Row 15 (port side), resulting in disproportionate focus. It was concerning that a steward had to personally return to apologize, a task better suited for supervisory staff. This highlights a development opportunity for supervisors Anna and Quashim in managing guest escalation professionally.

Flight was delayed due to slow boarding process by etihad. Update food options and movies as well.

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

we were delayed from Athens to Abu Dhabi by an hour and a half, so I had trouble connecting the flight from there to Bali. It could have been done had they waited even 15 mins. There was another lady who was in the same boat. By the time we were half way across the terminal, they have actually already issued different flights for us to go Jakarta then to Bali. Not to mention the inconvenience of waiting over 4 hrs at the airport and the subsequent inconvenience, we did not arrive to Bali till after 800pm the next day, which means I paid for the hotel for nothing when I could have been there before noon the next day! There was little explanation. It was just as well I needed some assistance getting around, otherwise the 2 of us would have been completely lost! Not going to fly with them again!

Boarding was efficient, had to check in cabin luggage. Seats were narrow, food was more in quantity, received cabin luggage on the luggage belt which was fine.

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.

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

Very punctual, the onboard staff was friendly and correct, the flight was fortunately very calm, the toilets were clean, in short, an excellent experience Thanks

Ordered Vegan meal - it was ok, but not exceptional. Seat ok row 39 middle section aisle. Nearly full flight - crew was busy but they did the best they could. There was a USB A port at the seat. I listened to my own music and only looked at flight information. One nice thing was the connection information was made available in the screen.

Very nice and friendly crew. Boarding system can be improved.

The Etickets had been changed (Why?) without notice ; Hence, that caused troubles when checking in. Not until I contacted my ticket agent and was given correct Etickets could I then check in.

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.

Several delays. Next flight was worse. Did not arrive home until 2am PT

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

Everything about the flight was lovely…We left early, arrived early, cabin crew were efficient and helpful. Flight was easy and most pleasant.

First world problems, but still… We were seated in first class and asked for a cocktail on a very short, 50 minute flight. After our drink order was taken, a half hour went by, and we noticed that every other person in the small plane had been served except for us. We got up to ask about it, the drinks finally came, then were taken away three minutes later since the flight was so short. Really strange situation, on the other hand, we were in Utah.

We missed our flight. The boarding pass had the wrong gate and by the time we received the text from Kayak, our flight was already gone. I’ll never use Kayak again and will go direct to the airlines in the future.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Cabin felt crammed Snacks are lame But crew was super efficient getting us out on time despite delay

Took off on time and successfully avoided weather that looked to be a problem along the way

There were five broken seats on the plane. The crew was very rude in telling people they had to get off the plane and get a flight the next day. No call for volunteers, but telling people they had to get off. One woman was flying with her elderly mother and daughter and was told she had to leave or all three had to leave. Fortunately, a volunteer offered to stay. The situation was handled poorly.

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.
