http://www.airlinequality.com/Forum/silk_air.htmjudge for yourself...you cannot claim any of the airlines are perfect.
there are pros and cons.
you can argue until the cows come home but it's pointless afterall.

if you experience good services from one airlines and bad services from another, it doesn't mean those airlines are good or incompetent all the time.
you have to read those reviews to have a better judgment since it is written by various of people boarding different flights and destinations at different times.
in the end it's all about the size of your wallet. if you have extra money and can't tolerate cheap services, please opt for premium airlines.
as for me, i can tolerate the lack of services as long as i don't have to fork out a fortune to travel. i just want to go to point A to point B. as long as i can reach to the destination safely then i don't have any complaint.

Our latest experience with Jetstar on our flight back to Singapore from HCMC left a sour taste, and made an otherwise enjoyable time in Saigon, not so great.On a budget flight we may be made to tolerate things like cramp spaces between seats or the lack of service or food or drinks etc but we did not expect rudeness! After the 'bad' experience we decided to write to Jetstar to let them know of their staff behaviour, but it has been three weeks now, and they have not even bothered to respond.

Singapore-Bangkok. This is a budget airline, and there is nothing to be thrilled about. You get what you pay. Having said that, here are the positives: You select your seat beforehand; You get to use Changi Terminal 1 and not the budget terminal. The negatives are: Extremely tight seat pitch, although the A320 is more spacious than the competition; Only snacks on sale.

Singapore to Kuala Lumpur return. Connecting from long haul flight from Zurich. Only criticism is meagre baggage allowance of 15kg. Had to pay for excess baggage. Aircraft used A320 brand new and very clean. Cabin service professional for budget airline. For a budget carrier streets ahead of European budget carriers. will fly with them again.

KL-Guilin-KL. Flight from KL delayed for almost 1 hour and everyone just sat there not knowing what was going on. Only upon my request for the pilots to keep the passengers informed did the captain open his mouth to explain that we were waiting for a replacement flight engineer. The Guilin-KL flight was outright stupid. There was a queue but passengers just barged into the front of the queue. The Chinese ground staff (which should be fired long ago) were indifferent to the disorder and couldn't care less. Tempers flared. There were shouting and shoving. When express boarding began through a side gate, there was no proper announcement. We weren't sure if we were in the right queue. I was travelling with my wife, 2 old folks and 2 small children and it was like scene from the last refugee plane out of Vietnam. Not a pleasant experience at all. I wonder why Aiir Asia would not implement seat allocation. It would have cost fractionally more and most would be happy to pay for it. The present arrangement of rushing for seats just doesn't work if travelling to places like China, Indonesia and India where order and courtesy to other passengers are totally disregarded. This was my last international flight on Air Asia if I can help it. Air Asia - not recommended for international flights until they implement seat allocation. We also suspect Air Asia would run into safety problems because the planes were not inspected thoroughly enough to make the return flight. The crew also looked tired and overworked.
