Having had a look at Jetphotos of British Airways, it seems the regular is an A319/B735 in the late 2000s with A320s mixed in and the occasional A321. Then throughout the 2010s its the same slowly moving to more A320s towards the end of the decade, obviously without the B735’s as they were retired at the end of 2009. The 767 does show up many times at Zurich in 2017 though so I’d love to have it as an option.
These 2 fellas were a regular feature in 2012 with the Golden Dove showing up until 2017 regularly (Torch Relay),
Both would suit ZRH and LHR as specials as well as nearly all the playable airports in Europe.
