Not quite right, Loc Green. I know of low timers who have recently got jobs with GB on the A320 and BMI Regional on the ERJ-135 - and not through any of the three routes you listed.
Fair enough, I did say "off the top of my head". I know a guy who got into bmi regional in fact so I should have remembered that one.
The fact remains that Britannia / Thomsonfly are in the minority of carriers who are at the moment hiring the low-time non type rated people.
Out of interest did the people you know who got into GB / bmi come from an integrated background or a mix?
