Having worked with both aviance and Servisair at CWL in a position to liase between my ex airline and handling agent I can say both were very good. We swaped to Aviance and ok there were some teething problems (we were a new airline in a new base aswell) but avaince soon pulled round giving us a very good OTP. They have a very friendly team with a very good manager who is very dedicated in his job. So its just down to buisness if one person offers the same job for less money then your goin to take the option to save money.
