How does this strike you?
Not ex-Scotland but coming back that close to New Year is going to seriously limit your options regardless.
800 TP, too, so well within TP run territory, although only one qualifying flight if that's a concern.
This also won't be easy to ticket - your best bet is to run it through Kayak.
Edit: what do you know, it's not that bad at all:
At that price, I'm actually quite proud of myself!
