Hello

I'm booking a club reward flight in August 2025 (BA 56 or 54) to Johannesburg and can see BA fly the A380 and 787. How can I find out which 787 version/can anyone tell me this? At present they are not using this aircraft.

I want to find out prior to booking as is it's a 787 with suites (787-10) I'd prefer that over the seat in A380 (but prefer quiet upper deck a380 over 787 if seats are equal!). I did want a First seat but these are impossible to find! I have lots of airmiles and a companion voucher (4 pax total).

Thank you greatly in advance for any help.
