Lvl chg, I fly the 747-200 out of manchester, the frankfurt and paris bases also fly the classic. The -400 flies from Lhr and also the states but does more boring, not so interesting socialscene stuff!! If you want the other a/s types you must go to HK for a year (once they release you off the freighter) and can bid back to LHR (-400) or paris/frankfurt (-400 or bus) on the pax fleet.
Pilot 74 most fo's on the cargo are either ex-mil or average experience fo's with commercial experience. I had 2000 hours in commercial light jets/turboprops when I joined. This is probably the minimum. What is your experience level?
