Yup, in the distant past we used to be able to check bags in at Downtown Disney VS to LGW then BA upto EDI
Most would do it if asked and you used to pick your bags off the “customs” belt in Edinburgh. (That was the belt with the *ahem red phone) Probably stopped around 10 years when the interline agreement Virgin had with BA finished and it just became a flat no !
Stopped asking them and haven’t really tried since then but I expect it to be the same now.
Strangely enough, if doing an MCO to JFK with Delta then onwards to LHR with Virgin, the Delta agents at MCO are usually the ones asking if you’d like your bag checked through to Heathrow with no issues whatsoever even when booked separately
