Thanks - interesting stuff. By how much has FRA reduced in frequency compared to say 2013? I recall BA even used to have a 767 on that route for a while on some rotations.
Picking a random day in September 2013 (so not in school holidays) and the equivalent day this year, it’s a reduction from 8 to 5. Aircraft mix is roughly the same, other than the 767 - but this was largely for cargo rather than passenger capacity anyway (there’s also a separate flight operated by DHL with a BA flight number for a similar reason).
BACF LCYFRA has remained the same at 4, though with some small upguaging as the E70s were retired.
