I ended up giving the CAA a ring today, seems they have a backlog of applications and told me it'll be at least another 10 days, not taking into account their closure for the Xmas holidays. Therefore it looks like I won't be able to get in an aircraft for a good few weeks
As has been mentioned, why does it take so long and why can't a temp license be issued? Very strange. Anyways, if that's how it is then that's how it is.
Hope all the other PPL holders reading this aren't taking this crisp weather we've been having in the UK for granted! I'd do anything to get up there!
Merry Xmas all
