I worked in customer care with Servisair at GLA. Funnily enough I do believe that the airlines like this kind of experience. Ive seen a lot of cadets that have been cabin crew or ground staff and it shows that not only are u keen on the industry, but u also understand the working environment and the long tiring hours. It almost lets u live the lifestyle of a pilot and there is plenty of time to speak to flight crew around you and learn about aircraft and airport operations. I think its the best sort of experience to get, it certainly seems to have worked for a lot of people.
