AA and AS have both almost zeroed out any saver availability for the foreseeable future. Prices of tickets have gone through the roof. Typical tickets for which I could find awards easily and where ticket prices used to be around $100 are now available only for $300 up to $700 or 30k miles or more in economy on AS and similarly on AA (How about 70k AA miles for a flight of1600 miles in economy?) . It is reducing my flexibility of last minute international award travel to nearly impossible. I have a few already issued tickets, but making new ones is going to be a pain for a long while.
So it is not surprising that almost all availability for BA Avios is gone.
