LGW PE Seat queries

Hi guys

Been a while since I've been in PE on the LGW fleet.. I have a Cancun trip coming up - just booked..couple of questions:

1) Entire seat map showing as 'not available' - is this because I've literally just booked?
2) Is it just row 75 that has exit rows, and are 70 and 81 bulkheads?
3) For exit / bulkheads, assuming none are available until physical checkin?

Many thanks.

I have a trip to BGI from LGW booked in PE in May this year and have been keeping an eye on the seat map. At first all the seats were available barring the front row (we're on an A330, I assume you are on a 747), but now there are only 2 single seats left in the cabin available for allocation. I assume the remaining travellers will get allocated at checkin and that the front row will be up fro grabs then if there are no babies booked. We're quite happy though as I booked the back row so we can have guilt-free recline!

Also confused as in seat map on my booking, not showing same config as I thought it should be

The seat map you are seeing Andy is for the lgw 747, the bubble is split between PE and E with the front 5 rows being PE. We always take row 24 for the guilt free recline,(as LucyLu says). I think this configuration came into use about 2012. Sometimes the seats show not available as I think some are kept back for VH.
