Hello, I may have to divert a LH flight through HEL and take the short haul route HEL-LHR. The route is served by an A350 with premium economy seats. If you do an economy booking from scratch those seats can be selected for a £65 fee (you do not get PE service, just a larger seat for the SH flight).

Does anybody know if as Gold BA member I will be able to select PE seats for myself and other passengers in my booking (one silver, two blue)? Thanks!
