AMS-LHR:
your questions over the last few months have been enjoyable to read and to respond to.
your energy and excitement about your new job has been nice to see/experience.
it brings back similar memories of how i was when i first started flying.
i wish you the best of luck for your training course from monday onwards - i'm sure you'll be absolutely fine. do your best to be an 'all rounder' on your course: with exams; speaking up in class at the appropriate times; team work etc etc etc in order to get one of the highest places, seniority wise, on your course.
seniority probably won't matter that much to you when you first start but later on in your career it could mean getting a transfer to longhaul 6 months before the person below you, or part-time 2 years before the person below you, or promotion to Purser or CSD long before the person below you etc etc etc.
but most of all enjoy it. the course is so professional and the trainers and facilities are fantastic.
enjoy!
