Better Avios availability when adding a connecting flight??
For the date I would like to book, there is only 1 award (Avios) seat available in Business MAD-GRU.
However, if I add a connection, e.g. LON-MAD-GRU or even a Spanish domestic like PMI-MAD-GRU suddenly there are 5 seats available...
Is this a bug in the web booking engine or do they load different (better?) Avios availability for through connections?
I've seen this before for revenue booking classes but never award seats.
