Mikehoncho - sounds like your the first person I know of who have been offered a permanent position as a First Officer. Well done.
Have you been given any idea of start date?
Ecam - interestingly in the presentation by the easyJet HR team the amount per hour on the flexi contract is based on current factored hours. This was clarified in the presentation. I had been previously led to believe the amount varied with the numbers of hours flown for easyJet. At £67 per hour x 750 hours I would be on a salary of £50,250 pa for the first 12 months. That doesn't seem right as you would then take a drop to £38k when joining on a permanent contract as an SO.
Think I'm more confused now than I was before!
