my brother will pick me up at ALB for immediate transport to Massachusettes; Assume then I dont have to worry about the NY quarantine, is that right ??

Just fill out the form and free to go.

I know about 4 persons who came from Florida. Not body has to quarantine. 1 arrived to Albany Airport and 3 others to JFK's. About MA really I dont know nothing.

I know they are handing out forms to people who come from out of state as part of contact tracing. My guess is you will have to fill out the forms and then follow MA rules for quarantine

Depends on where you are traveling from. You might have to fill out some forms, not sure. I haven't flown to Albany since the travel ban.
