Thanks crosswind.
I had figured that a guaranteed job was of course a huge bonus, but you are bonded for 5 years post training - which on a salary which is lower than expected, is quite a long time. Yes, there are many plus points to the flybe sponsorship, which is why I shall apply, but you also have to consider the negatives - nothing is ever plane sailing!
Thanks to all who have replied, all comments help to complete the picture.
