Don't Get Too Excited Folks!
Before anyone things wow, a quick way into the airlines with what are after all, a progressive and reasonably well thought after company.
Check all the stuff on the Terms and Endearment Section under the Jet2 Hiring very long thread.
The contract for non type-rated FOs is pretty shiite! It truly is a pay to fly contract. Yep the 70% contracts may go at some point but the nett pay is not good as it stands. If you just want to fly then go ahead and apply...just be ready to open the wallet very wide and have it emptied with no way to fill it back up unless wifey has a well paid job or you have a private income.
If they offer a special contract for ex-mil guys on this trawl then go for it but if it is on terms friends were offered recently......and they were guys about to leave the RAF....then think carefully.
