I just completed my App, using the link they put on the email sent to me advising it was open.
I had done the flightglobal application the other day and received an email from Jet2 advising to apply again today, but as you say this morning it wasnt open.
However, later on today I received an email advising you could now apply.

Same thing for me! Everything worked!
