Seeing same issues. Had a number of awards I saw on EF yesterday and verified on BA last night. Verified via EF again and transferred some AMEX MR's over to BA. Now, NOTHING is showing on BA for any date as I sat down to book them, LOL.
EF showing tons of availability, as is AA (via low level awards). Something is broken.
For reference, looking at Y and J awards for CLT-AUA/PUJ/GCM.
