I have travelled a lot on intenational airlines and among those airlines my favorites are Swiss Air and KLM. The service is superb and the best part is you have an excellent variety of food and drinks. Air crew is very friendly and service more than your expetations. Infact, I am also gonna fly to AMS this december on KLM..
I would always recommend this airline to all and every person.
Always fly to any location via this airline only.
