We're considering an Avios redemption LHR-BOS in F on a 14F 777 flight. OH is a very, very nervous flyer and consequently we usually book middle-pair seats in CW so I can hold her hand if it gets bumpy.

Can anyone comment on how practical it is to hold hands between middle F seats on these aircraft, and whether there's anything favouring 2E/F or 4E/F (the pairs currently available)?

ETA looks like the aircraft is a 777-300.
