I know things have changed a bit so I wanted to see if someone can offer more feedback.
I actually wanna to go SFO-POS but schedule wise there are not too many good options. So this is what I thought about doing
SFO-NYC/MIA and either over night stop or long layover (avios)
NYC/MIA to POS with avios or AA miles.
I also have UA miles but would rather use AA/BA.
AA has LAX-JFK in A321 flat bed. Is there an option for SFO-MIA?
