a longer gap btw the supper and breakfast would have been better - felt like the sleep was way too fragmented on this red eye flight

Food was terrible , uncomfortable seats, WiFi did not work, will never fly Singapore again.

Never book through Kayak. They can offload booking to third parties that are completely horrible.

Kayak really screwed up by offloading the booking to a third party. They were completely inept and caused a bunch of toil. I will never use Kayak again.

They ran out of the second choice of food was stuck with fish

Airline should consider adding a small meal at the last leg of the flight, right now there is 7 hours of no meal break.

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

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.

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

Perfect experience from boarding through to leaving the flight, comfortable and personalised service from all staff, highly recommended

the rudest staff in the world!!! we had overweight baggage, which is our fault but it is a really stupid rule, and the woman said we could reorganise or pay now, we said we’d reorganise and she started shouting “do it now! hurry up!” even though the flight wasn’t even boarding yet. She told us that if our two cabin bags were below 14 together, then we wouldn’t have to pay 500k dong. We reorganised and our bags were below 14kg. She then said that it was all of our bags together that should be less than 14kg. We were obviously confused by this, because she had just said that it was our two cabin bags and we asked her why she told us to rearrange our bags then. She started shouting at us again saying that we needed to “pay now or throw away”. We said fine, we’ll just pay, and she suddenly started asking for 1.51 million dong. I asked her why it was suddenly over three times the price and she said that it was always that price. I asked to see the other piece of paper she had that had the other price and she slammed her one on top of it and started shouting “pay now or i’ll close the gate” (boarding was already finishing at this point). So, we had no choice but to pay three times the original price, even though we reorganised our cabin bags to be under the necessary weight like she had asked us to. I wouldn’t even be so upset about the money if the staff were at least a little bit nice. She was possibly the rudest, most ignorant woman I have ever met in my life. Besides that, the plane/flight was just a bit worse than ryanair standard. Small seats, delayed by an hour. Typical low budget. At least the ryanair staff don’t try to scam you. Avoid at all costs, it’s not worth the hassle of dealing with such horrible people.

Other than the bus wait time to off board passenger when we reached Don Muang, everything else was excellent

Very good, it would be good if payment for drinks could be accepted by card too.

Took 4 flights in 5 days 3 out of 4 left late about one hour each.

The boarding process was very poor - refueling on so rear ladder blocked. I think while boarding both ladders should be accessible so that passengers are comfortable instead of crowding through front ladder

No WiFi or movies. And the seat We’re uncomfortable. Good thing it was a short flight

It was on time! First time in a long time for Air Asia. Thank you!

We had a 3 hrs delay and they offer McDonalds pineapple pay. They charged us for extra grs of luggage and the experience was not good

Good, no mini-tv's, no food unless you pay, good overall experience.

ได้นั่งรถไปขึ้นเครื่อง แอบเสียใจอยู่ พอขึ้นไปถึง มีคนมานั่งในที่นั่งเราอีก ไม่รู้เจ้าหน้าที่บนเครื่องไปแนะนำผู้โดยสารท่านอื่นยังไง เขาเข้าใจผิดว่าที่นั่ง C คือข้างหน้าต่าง และเที่ยวบินนี้ ดีเลย์แล้วดีเลย์อีก จากทุ่มสองทุ่ม ดีเลย์ไปถึงห้าทุ่มกันเลยทีเดียว ถ้ามีไฟลท์ต่อกันนี่คงไม่รอดแน่นอน
