Someone will be able to post a more definitive response.....but today's class of 32 was offered something along the lines of:
GUM 737: Up to 3 slots available.
LAX 737: Up to 5.
DEN 737: Up to 10.
EWR 756: 5
Remainder of SFO 737/SFO 756 and EWR 737: split 50/50.....

I don't have details on how many of each were taken.
