Thanks to both of you BA6501 and corporate-wage-slave for your advice and welcomes. Another long time reader of the forum, about time I joined in the fun I think!!

I think I will go for 20F and then if it turns out to be empty, move to a row of 3 after take off, it is a night flight anyways so the lack of a window isn't too much of an issue.

Slightly off topic but I am actually flying Doha-Baku-Heathrow-Manchester, because why take the direct flight right What are the chances of Qatar groundstaff in Doha being able to check my bag all the way through to Manchester with an 8 hour connection in Baku?

Now to try and get my head around the Azerbaijan Transit Visa situation
