In general good, but the machine seems to be long in operation and some functions were restricted as e. g. Adjusting of seats.

In general good, but the machine seems to be long in operation and some functions were restricted as e. g. Adjusting of seats.

When boarding, after business class should be premium economy, but economy class already lined-up at the gate blocking premium economy to board. Singapore airline crew should done a better job to organize this chaos :( Thank you.

It seems paying premium economy does not make difference with economy. No priority boarding, not worthy paying extra$$$ for premium economy.

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

They were able to assist my elderly father and myself after not being able to check in to scoot. The counter service was phenomenal. They did what they could to get us on the next plane so we could catch our Connecting flight. Scoot closed early on us so we ended up missing our flight.

They are great with every aspect of customer service. Helped my elderly father and aided him with using the restroom.

The stewardess was very helpful all the way. My seat had an issue with headphones and after the replaced and gave me a new pair and noticed it was the seat I got a new chair to sit and a great ride back home

Due to the delay of my first flight, my connecting flight with JetBlue was canceled by Singapore Airlines, but the JetBlue crew was very accommodating and rebooked a seat for me. The crew was very nice and had good attitude.

The overall operation needs to be improved. The in-flight services took forever and sometimes ran out of options.

Flight was delayed by 2 hours. No entertainment on the 737-800NG. Somewhat squeezy.

More facilities to transport to the gates......felt too much walking distance

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

It was good no problems made it on time for the next flight overseas!

It was a really long flight from Doha to Philadelphia and it was overall a good one. The one area that I would comment on is that there is a lot of single-use plastic and disposables in the meal service for American Airlines. It would be great to see more circular options in the meal service to reduce the amount of waste.

Suddenly Flight has been change by Qatar and there’s no information is there of us from Bom to Doha and counter person is behaving like Qatar owner next I will not buy Qatar and I will not suggest anyone to fly in Qatar

The crew was fantastic and the over flight was perfect as well.

They shld provide food. Between food they are giving 10 hours gap which is toooo much

The crew was great and the food and liquor offerings were good. Seats were a bit cramped. Flight arrived early at destination. That's a plus.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

I had already opted for Vegan food before 2 months yet they say we have no record for it,

Food could have been better Entertainment was absent even in Business Class

I like it very much. Gulf Air is always the topper rank of the world. I love it very much.

The drinks should come before food. Unable to have any fluid unless after food. Thanks

Gulfair were on top form and everything went as planned

The entertainment on board was really poor. The map doesn’t give enough information and the movies have arabic subtitles, you can’t choose. The stuff wasn’t very friendly and the breakfast really poor. The food must not be spicy! They didn’t have enough drinks.

Aereo nuovissimo e con tanti servizi malgrado la durata del volo Spazio per le gambe ridottk

It was a great experience, can’t wait to do it again soon!!

Aircraft was new and comfertable .on time. Cabin crews, which I got english language pronounce was very difficult to understand .ovee all ok flight

The boarding at Heathrow is chaotic. That's partly due to the lack of space and seating at gate 8, and a Qatar flight from gate 9 at the same time. That's down to Heathrow rather than Gulf Air. I've had a similar experience here before. Another problem which isn't specific to Gulf Air or Heathrow is announcements, and those for boarding in particular. They are difficult to hear with all the other noise and for me with hearing problems it's even worse. A simple tv screen would help, so long as it's updated of course.

This itineray had to be cancelled as the connection time in Paris was only 55 min which is below the 90 min required by Paris airport. Nether Chat deal/Kayak, nor Gulf air nor American Air picked on that. I called American Air for unrelated question was then told that boarding would be denied due to the short connection time. This should have been an automatic notification from Chat deal/ Kayak or Gulf air and itinery cancelled. What is the point of inconveniencing the passenger?? The return has still not be refunded. Shame on Gulf Air, very poor customer service for an airline that has so good flight crew!

Loved the check-in experience. Very friendly staff and not crowded. I did wind up with a middle-middle seat, which was quite uncomfortable. Always appreciate the very professional staff on TAL.

Paying for reserved seats and never received the seats I paid for !! Just fake and a surprise out of their " box "

Turkish airline always good Only Turkish representatives at the gave need to be more helpfull to any staff who traveling on Turkish airline . One situation happened Ist to jfk on Feb 29 TK3 had seats I asked them to transfer me to tk3 because Feb 29 tk1 was oversold and they advise me that I might not make it for tk1 I asked them to transfer me to tk3 and they say no they can’t do it I been telling them you know that I don’t have a chance for tk 1 why would you let plane go with some empty seats on tk3 if you can transfer me to tk3 and have less staff on tk1 and still told me no I waited for tk1 9 hours and only last minute I got seat on tk1 It was not easy situation but I am glad I made it home Thank you Turkish Airline One more suggestion for Turkish Airline you need to make a FIRST CLASS cabin it would be so cool 🆒 Good luck all the best See you more

First class payment but wife’s seat broken, would recline but not lay flat. On previous flight, delays and ground crew malfunctions connecting jetway made us miss flight to Houston. I asked twice for a cart to assist us getting across the massive Istanbul Airport, but was denied. We are both over 70.

My flight had two legs. When checking in at the first leg the agent offering for a deal to upgrade the leg to first class for $199. He then claimed I would be able to upgrade the second leg once I got to the next airport. I declined and when I inquired about upgrading at the second airport, the cost was $1,300. I also had an issue at the airport lounge. I am allowed one guest in the lounge. My friend came in the lounge for less than 5 minutes and left when she couldn’t get a sleeping suite. I wanted to bring in another friend. The airport staff first started acting as though they didn’t understand English and then became upset when I asked for their names so I could file a complaint. As an elite member I knew they could do more but were not. One of the agents started over talking me and walked away mid conversation dismissing my request for assistance. A man claiming to be the manager said you were asking for her name. He also never tried to assist me or see what was going on. He claimed the interactions were recorded and management would see everything. I’m not sure how that would assist me days later. I am sure it didn’t help that I was a black American woman.

Better attitude training for staff at airport, better training for flight attendants, better food, don’t put us with all the crying babies that cried nonstop for 12 plus hours.

Crew announced boarding started and they asked passengers to form a queue. Actual boarding didn’t start and queue was not moving for around 40-50 mins. Very poor management.

It was a terrible airline. The air hostess and the people in the flight, just very rude.

Crew on this flight was terrible. Especially one practicular female , she was harassing us and other families with children. Flight was good overall, if not her being rude and aggressive

Istanbul to Miami Sector the plane was nice and clean except for no WiFi during the entire flight. The flight from Karachi to Istanbul was another story .The sad part is we paid for business class to be comfortable. The foot rest didn’t work. The flight attendant had to push the seat to put to recline position and/or put it back. This was not only for me but for other passengers in business class. The tray table would not come out so had to get help from the passenger sitting next to me. I understand that they may have to use old planes but Turkish Airlines have to make sure that the things are functional especially the duration of flight is six hours and they are charging a lot of money. It seemed that i was flying a domestic sector instead of an international flight.

As usual invariably delayed Lots of time in getting chkd in baggage

Staff needs to be trained in managing customers better. Indigo appears to be a low cost airlines in all aspects.

Flight was delayed and also lots of mosquitoes on the flight

Two times the gate was changed and flight got delayed

INDIGO Never On Time & Always Prefer to Shuttle Passengers Like shuttle Corks

Seats don't recline, no charging points. New aircraft and very clean. Crew should serve some water atleast.

Wife and I were seated in separate seats across the aisle

There was inordinate delay without any plausible reason. This has become a normal feature of Indigo now a days.

Flight was inordinately delayed, which has become normal with Indigo. Crews were inattentive. After landing there was a lot of time for arrival of chek in baggage

The entire experience leave an impression that there are scopes for improvements in all spheres. Seems the airline has expanded beyond their capacity to manage.
