Sound me out people.
Is it not something like....
1st year as a cadet circa £18k
2nd & 3rd year - fixed term contract as a second officer circa £41k/yr
4th year - signed on to permanent contract as first officer, £45k rising to £57k plus flying pay, pension and perks?
Easyjet has DE contracts on offer for first officers in Europe, probably as part of their 'turn Europe orange' plans. Maybe you would get a perm contract quicker after training if you were willing to go to the continent??
All speculation on my part folks....
