If this is your first job then grab it with both hands. Forget the shiny new E195. Its the job you need. I left Flybe last year and I think the 195 may be dead mans shoes, especially if the job market starts to dry up. Don't forget that Flybe jet fleet will be a fraction the size of the TP fleet and I believe that the ex BA EXPRESS crews will now be eligible to bid for the jet. When the market is going the way it is you must be absolutely flexible in your approach. focus on the now.
I will add however that I had 7 very happy years there (Bae146)
