Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

Three meals on a single flight is disgusting. Even if I reject them all, sleeping is impossible and all that food (especially wasted food) is just antithetical to a pleasant flight experience. People were chucking multiple abandoned trays on the floor in front of my seat.

Hospitality is good. Should improve on buggage handling because l lost a suitcase. Layover in Dubai was too long , 6 hours

Emirates need to improve the boarding process. There is no point calling for all First and Business Class passengers plus Platinum, Gold and Silver Skywards members at one time. Further to this, try channeling all these people into one entry point with no defined lines. It was chaos. The is a common issue on the Dubai to Riyadh flight. Poor effort Emirates.

I lost my lock from my luggage, I don’t know someone took something from my bag.

The flight from Beijing to Dubai was good. The flight from Dubai to Barcelona was excellent because of the staff on board.

The queue for checking for economy passengers was enormous! Only one desk open for economy faith s queue a mile long, whilst business and first class desks empty and unemployed. Will seriously consider changing to another next trip. Disappointed customer.

They should resume the fast track for business / first class passengers

Everything I was good except food quality is very poor

Flight was delayed by and hour but were informed beforehand

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

Good. It would be great if comfort seats were available

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.

It was excellent in all respects. I don’t think it needs any improvement

Terrible experience resolving missed connection after flight was delayed. 3 hour queue at transit desk, not enough staff, no organisation, worst ever flying experience.

Liked some flight attendants. 1 was rude I'll not say her name I don't want to get her jn trouble on my flight back to Dallas from Doha. Very rude to some races of people clearly. She needs a better attitude and bedside manners. Asking her questions and she responds "WHAT" twice rudely like I was bothering her and "is it going to be cranberry or mango juice with an attitude".

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.

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.

Do not overbook flights and kick out confirmed ticketed passengers :-(

Did not provided with option for class upgrade. Staff at gate was not able and willing to accommodate with class upgrade, eather with plenty empty spots in business and first class.

I am a larger than average person and in my opinion i don't think it's fair to allocate a window seat to anyone who is my size or larger, i was seated between 2 large passengers on a full aircraft. The guy in the window seat also occupied a portion of the middle seat (my seat) which made my experience of flying with etihad very cramped and uncomfortable, i was flying from Abu Dhabi to Bangkok. Had this been a airbus 380 it would have been better as the seats are larger but unfortunately it wasn't so i had to endure the 6+hrs unable to get any rest

It was worst flight ever of 26h. Poor service and seating. Flight from Abu Dhabi to Islamabad service and seating was worst ever. No tv extra.

i was not allowed to use lounge, although i had business class ticket, and nobody told me my ticket was not eligible to use lounge

It was OK as the seat which we paid for doesn’t have any window. We paid $120 for 3 seats but it’s for nothing. Crew could not help. None of the ports worked so all our phones went dry

A380 First Class Apartments were phenomenal. Comfortable bed and matress cover, superior vegetarian five course meal, shower, small business lounge and plenty of exercise walking around the aircraft.

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.

Horrible. After paying for my seats, I was cramped, had no overhead bin space, freezing as the flight had no temperature controls, the food was awful and served cold, when asked for snacks was told to wait and then never received any. I booked this flight as a partner through American Airlines but will avoid in the future.

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

Paying extra for premium seats was wasted. Turkish Airlines takes 2 seats for bassinet. The lady next to me had a baby with bassinet Bassinet was in front of my seat

It was pleasant except for the boarding at Istanbul and long wait for the wheel chair almost missed the flight Itambul to Dubai

I was sitting almost in the back, the seats are very tight and there’s no legroom, it’s uncomfortable for a long distance

It was great except my luggage was C severely damaged over i picked it up off the carousel in London. . A suit case that had been used once does no longer have the use of the extendable arm as it’s broken

About an hour delay but we made it to Chicago. I feel that the smaller connecting flights are the ones that cause the delays on the bigger planes that fly international.

Amazing! Big line at Check in was diminished in 10 minutes. Boarding was quick and efficient. Service and food great. Only minor point: seats could be a little broader and for me being small, something to put your feet on during the flight would be great.

Turkish airlines have improved a lot, please keep up the good work.

No customer service. Non educated staff members with no will to support or service the passenger.

My wife and 7 months old baby had a terrible experience traveling, we paid extra for bassinet they didn’t provided.she missed her flight due to late landing of the flight, they were unsupportive to my family due to that my wife and kid suffered a lot.

I’ve been traveling for 20 years. I tried Turkish airline for the first time horrible horrible service and it would be my last time even if I get offer for a free ticket, I will not accept it. They have races and the worst Flight attendant

I noticed the crew was so much nicer and friendlier. It would be nice if British Airways would serve soft drinks during the flight

Must have had an elderly tour on the trip. Plane boarded via tarmac and had both front and tail stairway access. We waited about ten minutes at the rear entrance while elderly folks entered the forward access and walked all the way back to last rows of the aircraft! We could not access the row until every one of them finally reached the final rows. There should have been an agent directing folks Forward and Aft based on seat row. It was comical.

The airport experience at check-in, just to drop a bag, was horrible. The were two agents working, two watching. We stood in line for just short of one hour. I asked the agent if this were normal and he said, "Well, yes. Just two computer terminals." No apologies. BA needs to fix this ASAP. Meanwhile, I've moved BA to the very bottom of my booking list.

Good shuttle to Europe. Face check boarding needs overhaul. 2 stations for 200 people and still with passport check. Why have both? Why is this now slower than 5 years ago?

Tickets get checked 4 separate times by different staff, would save time if only the person at the entrance and the person who scans the tickets checks them!

I have always been pleased with their service. Would not change a thing

Both flights Heathrow and to SFO were delayed significantly. Walking up outside steps to aircraft with suitcase was a challenge and I am a healthy 63 year old!

Why don't they board from the back of the plane to the front. We have to move by all the people and their luggage to get to the seats.

Seating and food was the worst we have experienced in 35 years of traveling for both personal and busines .

First of all, our gate, and perhaps all of British Airways' gates for Nice-Heathrow flights, led to a series of buses that took a long time to board, were crowded, and offered virtually no seating. The long line of passengers moved slowly. The food in business class was awful. There was an air traffic controller problem that caused our flight to be significantly delayed, and many of the passengers had connecting flights at Heathrow. While the crew acknowledged our concern and promised to give us specifics about where to go when we landed, in fact, no announcements were made, so passengers in that situation were anxious about how to quickly find their connecting flights. Not a great look for BA.
