JDiver

We’ve a 77A three class 40J seat aircraft from OAK to LGW, according to BA MMB, 18 Aug 2018. (BA Source suggests it’ll be a 77A 40J, but MMB says 77A).

I know 4E&F (and 11E&F) are “honeymoon”seat pairs with aisle access immediately aft of the adjacent seats - and that as the E seat offers a baby cot that these are not available to non-baby adult passengers until close to departure.

Am I correct the other E&F pairs require climbing over recumbent passengers in the D or G seats? Is that true of 1E&F? I prefer these as I must administer medication to Lady JDiver in flight, but I can do so in the seat pairs with the privacy dividers - or from the aisle if she’s in a B or J seat.

At this time I have 4A&B booked, as AFAIK 4A can access the aisle via some space immediately aft if 4B, and I can administer care from the aisle.

I’ve not flown BA 777s, only 747 and A380, in terms of widebody aircraft.

Your advice would be appreciated. TIA!
