My mother (late 70s) and one of my siblings will be on BA 15 in Sept and I would like to book them good seats. This will be their 1st time with BA and their 1st time ever in business class. Coming back from LHR they are on BA 11 to Singapore then BA 16 to Syd. We have paid the extra to select seats, as I couldn't risk them being seated apart, so at this stage they have 14a & b on BA 15 and BA 16; 18a & b on BA 11 - just wondering what would be best for them? Any suggestions from flyers who know these routes and the BA product would be greatly appreciated as I want this to be a fabulous flight for them both. Thank you
