BA182 on the 20th Jan is currently scheduled for a 77F (RR Powered 4 class 777 G-YMMG through P) which are all fitted with Rockwell Collins' Total Entertainment System (TES). Ths system is BA
's first generation AVOD so what is listed on BA
.com will be available onboard as long as the system is working.
There are just 8 777s which do not have AVOD (GMIS 12 channel loop) these are G-ZZZA/B, G-VIIC/E/F/H/N/S. These aircraft are being upgraded to the new Thales IFE. G-VIIH is currently at Cardiff being upgraded.
Hope this helps
