I loved the comfort of the flight and the hospitality of the flight attendants!

They ran out of food for breakfast They did not offer tea or coffee The staff appeared very inexperienced The cabin was very cold, even with a blanket

If I made the connection in Singapore I was stuck there for 24 hours you owe me 355.00 for accommodations

plus: service and personal assistance minus: online check-in did not work

Great to have actual hot tastey meal on a flight. Well done

I requested an aisle seat and got a middle seat The flight gate was changed and the flight was delayed

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

Cabin Crew always friendly and helpful. Seating cramped - foul smelling from toilets, high risk of disease. Guard personal property such as expensive sunglasses Coffee always awful and cold Meal trays toddler sized Not worth the extra cost to fly SQ - use a budget airline, same if not better experience

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

Wonderful service, planes and interior in great condition, very pleasant experience

Absolutely horrible all around especially for such a long 13-14 hour flight - terrible food - ancient entertainment - legroom worse than a short air Asia flight - not enough toilets

More than two hours delay I could not do my tax refund because of the delay to check in They lost my luggage

Surprised how empty comfortable seats in economy were not offered by crew to tall passengers. Felt like courtesy hall mark of emirates is changing. We were told in order to get those seats we have to pay $210. Not the emirates I know from past travels.

Plane was old and seats uncomfortable but staff were friendly and helpful

Always my favourite airline. On time, lovely staff, clean comfortable seats. Well done

My last few flights with Emirates have always been delayed at least a half an hour. When my layover is only an hour and a half to two hours, 30 minutes makes a big difference. I’m going to check out other airlines.

Didn’t like it at all. Cabin crew unfriendly. Very bad experience.

Absolutely terrible delays for 3 hours changed seats after we paid an upgrade on both legs. It appears it’s up to us to request a refund after they down graded our seat. Never again !!

Good but needs to improve cleanliness Coffee serve cold Needs to raise standard serving food Otherwise good

More leg room and comfortable seats at least for long flights

Being a QR Platinum member traveling in business class, I expected the staff to be more courteous. Unfortunately, the lady staff was rude attending business class 1K side.

Overall experience was OK. Seats were truly uncomfortable for such a long flight. Food quality was mediocre at best. The staff was great though!

Noice cancelling headphones would be better since it’s a crowded plane And kids behaviors are unavoidable

Being a platinum member, no attention given. No towel or tissue provided.

Food was good, attendants were friendly. Seats were not comfortable. Did not receive any amenities such as eyemask or earplugs that would have helped sleep. Additionally a large group of passengers boarded very late into boarding and were a disruption for almost the whole flight. Flight attendants did their best but the kids were making so much noise, kicking seats, and half the time no adult was sat with them so they weren’t being managed.

Good staff, good intent, decent entertainment. More seat space would always be of benefit

No towels or tissue and chocolate and mint provided before arrival

They made us deliberate waste time by holding our passports and boarding passes making us miss the flight

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

Overall it was a very good experience. Boarding was efficient and well organized. The cabin crew were excellent. The meals were tasty and quite filling. The warm bread rolls were a nice touch. Seats were comfortable even if they were a little narrow. Entertainment selection was excellent.

Extremely poor. First - and oddly enough, Air France denied access to the Business Class lounge at CDG to all of us - although we were all flying Business Class. It is amazing that an airline denies lounge access to its passengers flying on business and paying several thousand dollars each ticket. Second, the food on Business Class on absolutely horrible. Air France must have made an effort to prepare bad tasting dishes (not even the ice cream was good). Third, the cabin temperature was too hot and although we complained many times, it never got cooler.

The first half from DC to Paris was very good and the staff were very helpful and humble BUT flight from Paris to Mumbai was sad. 1) it was packed. 2) no space on head compartment 3) crews were unresponsive to the calls 4) one crew member literally banged the bottle of water after giving me glass of water. A little water splashed on me and she was unapologetic 5) with so many hours of flight, little leg space should be taken care else don’t fill your airline till brim which affects your crew and they remove anger on us. 6) huge line for washrooms. 7) 2nd half journey was pathetic

Good. Food items are ok but not really healthy (no protein for the vegetarian option, just a total of 2 gr total) so not fulfilling. Also, no airline is educating passengers to behave and have common sense: let the one sitting by the window pass first, leave toilets clean after use, etc. Humanity is just getting rude and more disgusting by the day and without education or enforced common sense no

Old cabine without flat bed in business for a 12 hour flight is not acceptable

Medíocre. The food wasn't good (although not bad, bad) and the staff wasn't kind. I asked for n extra blanket, the steward never came back, serving us roughly.

Generally good. The crew is excellent. The food could be better.

They charge me for luggage which is was included on the ticket

Good aorcraft 777 but Worst food ever Breakfast was a bû’with matonnaise… Staff was nice but invisible most of the flight

Business class in the second leg - CDG-EVN was a disaster.

Everything went smoothly with Air France. There was a delay in departure which seemed to relate to the immigration services being short staffed.

Usual friendly BA crew who were helpful and so kind to the kids. New business class cabin combined with 787 makes for a really enjoyable experience.

Chicago to London flight was delayed an hour . Boarding process was slow . I missed my connection to New Delhi and My connection from New Delhi to Ranchi. Now come the really outrageous part! There was a flight from London to Bangalore that would have allowed me to reach Ranchi on time. I was about to but ticket from Bangalore to Ranchi when BA agent came back after talking to someone in back office and informed me that she cannot rebook me to London Bangalore flight as Bangalore was TOO FAR fro. Delhi. I waited 8 hr in London airport. I was flying business. Hope this review helps the airline. I was not asking for any money back for my missed flight. Anand Mohan

Excellent. The only issue was ground crew in the Venice airport. Not so friendly. But BA staff was amazing and apologized even though it wasn’t their fault.

Shocking. Bumped off the flight as they had overbooked and given my seat to someone else. Rebooked for 24 hours later with no effort to get me there the same day. Staff don't care if you are going to miss events...they give you a hotel voucher and that's it.

Horrible. Never again. Wouldn’t let us use the lounge. We had to pay for another lounge to have access.

Everything was quite lovely. The crew, the food, the variety of entertainment, the flight itself, etc.

British Air ways was good - American Airlines not: waited at gate for “mechanical issues” and stood at gate.. plane delayed, … staff at desk rude, had to check my personal carry on item, toilet not working… “please use the working one sparingly- it will overflow in the cabin”

The port to insert the headphones was loose and had to hold it the entire time

Lost bag on an hour and a half flight with no connections - ridiculous!

Boarding poor in London,ok in Chicago. Don’t like Heatrow/terminal5
