After “thumbing” through a number of pages and some searches on this looooong thread, my last resort is to post this. In addition, I have checked out BA web site (but did not follow through to seat selection) as well as seatguru and the OP. Am confused about the various versions of the planes.

Looking to book a BA flight LHR- DXB in CW. Out of the 3 daily flights, 2 are on 777 and 1 on 767. Have 3 simple questions:
1. Which plane is better (hard products & in-flight service)?
2. (from Post #406 link) Can someone confirm BA107 now equipped with the new 777-300ER conf? What about BA109?
3. Would like a window seat (DW travels with me), here comes the rhetorical question of “which are the best seats for couple” ? (I can see DO SEARCH coming )

Thanks.
