[QUOTE=miikkak;23873336] Those of us booking US coded discount economy tickets earn 100% Avios (also tier points)/AY Plus points while those booking AY coded discount tickets earn only 25-50% AY points or 25% Avios.

This, if I got it right: Assuming US/AY prices about same, IF I book on US, the discount Y ticket earns me 100% AY points (my FFP) even if AY is carrier, whereas on booking the same on AY I may end up with 25/50%? I never thought about that trick. But then I guess I will not be able to upgrade Y->J with AY voucher/points if ticket is US even though carrier AY AFAIK.
Thanks!
