Thanks for the good wishes folks - bricking it but happy I did the session, even if the cost did make my eyes water!
I ended up using Virtual Aviation - they got me 2 hours on the 737-300 at Luton - had to hare over there straight fomr the PPRuNe seminar at LGW! Good instructor and 2 hours was plenty of time to practice the profile I've been given. I'd recommend them if you can't find anyone else - they are very professional and organised me at short notice but they are top dollar (£1000+ for my session
). Still, if I get the job - who cares!
Roll on Thursday.
