The seats were more narrow than at other lines. Food was mediocre (economy class)

The seats were more narrow than at other lines. Food was mediocre (economy class)

The crew have great customer service but their economy seating isn’t the most comfortable for a 220lbs+ guy and the food wasn’t bad, but wasn’t exceptional, either.

Food option Hindu veg to Hindu non veg request was unheard

This flight was 16 hours and they made it very tolerable. Seats were comfortable and the staff very accommodating. I had plenty of inflight entertainment. Food was very good.

They made 22 hours aboard aircraft very enjoyable. I was very impressed with the attention to detail and level of service. Singapore airline will be my preferred choice going forward.

Service excellent would chose Singapore airlines as my first choice

We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

My groups frequent flyer star allianceUnited airline miles was not accepted. The Singapore premium economy bag had to be requested, it was very lacking- no toothbrush. I paid more than double than economy but could only use the bathrooms sharing with economy which was hardly available and had to wait in line. Is the 2X $ worth it just for a larger seat???? It is questionable. Seats were not that comfortable. My husband’s seat had white stains on it- had to wipe it down. Our headphones did not have covers on it. Food- way too much.

The booking experience was bad. Our six character booking ID number disappeared the day before the flight, We could not find out what happened or what was the status of our flight, scheduled for the next day. We finally found the right number to contact Singapore Airlines on the matter (not easy). The Singapore agent worked through the issue in a little over thirty minutes on the phone, the day before the flight. That was great. I'm very happy with Singapore Airlines and their performance. Contact with a competent person on the matter was near impossible. It seems no one in business these days wants to deal with customers once they've pocketed the money. There were resellers, including Kayak, involved in the chain. When we finally got through to Underpricer, we did get a return call that could have proved helpful. But by that time the matter had been resolved by the Singapore agent. Majestic Vacations, the reseller who received the payment was less than worthless. That's just a fast buck operation. Ugh.

Could not really fault anything. We had a really short time between flights (about 45 mins), and had to get across the other side of the terminal. But we made it and crew were helpful. Food was good and service for the kids was great.

Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

Transavia flight, was booked as KLM but i couldnt select seat or access boarding pass with KLM at all. Crammed seating and very no frills experience all around. First and last time.

Transavia flight. Couldn't select seat or anything prior to flight. No connection with klm systems. Seats are very crammed. Extremely no frills.

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

The IFE was quite old, but it worked fine and the content was good. The cabin crew were excellent and the food was as also very good

Great flight because I upgraded to Premium Comfort. Made a huge difference in the experience.

The flight was great, the only reason for middle scores on entertainment and food is that it was a short flight so not included (but snacks were served including alcoholic beverages free of charge). I would definitely recommend KLM.

Was trying to change a flight but told that Canadian and local klm systems do not interact so they could not access my booking. Overall I like klm a lot but if it was important to change flights I would be very frustrated.

Flight was delayed. Can happen. But the info on the website and app said that flight was cancelled which was not the case.

The whole trip was excellent. The only thing I would change is the temperature of the plane was a bit high which made it uncomfortable to sleep.

This flight was a dreamliner so I think the space was ok for the legs, but the option for food was again limited and the crew was same.

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

In never flown this flight, because my flight coning from Barcelona was delayed.

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

Seat selection screen while online check-in could include free seats to choose from and show the options before we proceed. Currently, it is auto-allocated and there are no options for free seat selections.

Long way to improve. Toilets not working. Bad handling when flight was canceled

Lovely crew - comfortable journey despite it being an older plane.

The business class experience is fantastic. The crew were polite but often unavailable even when I tried to call them! I even found myself bringing my used dishes and cutlery up to the crew because no one had come to collect it after over an hour.

Online was good boarding also but a child was crying all the way with no intervention from crew member.

1st time with. Etihad Airways and it was amazing from check in to crew. Great flight.
