Hi,
Congrats on getting that first job !
You shoud stand a good chance with quite a few airlines with a bit of jet time I would think. Not sure what the EZY requirement is, but believe a few hundred hrs on type? (check website). Don't know about BMI.
Last year at least one of the cadets got offered a winter contract at MYT Scandianavia, and they also have recruited quite a few guys/girls on a perm. contract this year, so who knows what will happen when your summer contract ends...
Good luck and enjoy the summer !
