There must be a thread to track first class routes on BA but I can’t find it, would be grateful for a pointer please.

At present I use the BA cheapest fares page to see the destination list but I don’t think this is necessarily up to date.

The problem I am trying to solve is determining where I can use GUFs to upgrade from J, for example Doha.

The page lists Doha in first class and I can see some flights available for purchase depending on the craft but seems like they don’t show up for exactly the same dates on BAH results
