If I were a turbo prop FO today looking for a career advancement on to big jets, then I would certainly apply to Thomson and go and see what they have to say. I think you have to look at it in the medium term, not the sort term and look at the deal with a broad brush. You can always say no to an offer if you feel you are being short changed. Moreover, if after 3 years say with 1000 hrs + on the Boeing you can always leave. The 738 is very useful time to have.
The 787 is only based at Manchester and Gatwick and that does nt look like it's going to change.
That's all folks!'
