Hopeful CC -
at the end of the day its all about attitude - we know that its daunting straight from GS and that you cant pick up EVERYTHING in the first day or two - no one expects you to. The only thing crew will expect of you, is that you come to work on time, are positive and a hard worker, helpful and if your not sure of something, ask! People dont expect miracles from new crew - we just expect some kind of positivity towards the job, you know, looking like your enjoying it, not rolling your eyes at passengers etc haha
Just that, and get out in the cabin as much as possible are the only things to keep in mind.. the rest will be a piece of cake and you will be fine!
