I'm shortly flying from Heathrow to Las Vegas direct with BA and looking to make sure I get the best seat possible (Obviously!). I'm aware of the long lines at immigration so looking to disembark the plane ASAP so my question is, where should I be looking to sit? I'm not rich or flashy enough to go Premium Economy or Business class, so having to slum it in economy. Judging from the seat map here britishairways.com/travel/worldt/public/en_gb
it would I need to be looking for either row 16 or 26, but I don't know which exit they disembark from (I'm guessing the don't exit from the rear). Anyone know?
