Pardon the basic question but it's been 10+ years since I've flown BA.

Flying solo in Y on the 77L configuration, the good exit seats are taken already.

26K in the 'mini cabin' and hope for an empty middle or take one of the twin seats at the back? I'm 6'3" so any extra space is nice. 3+ hour connection so no need to be off quickly.

edit: post-trip report: the extra shoulder room in the twin seats plus the extra legroom from being able to put my bag between my seat and the window was great. As for row 25? So. many. babies.
