Thought I'd bump this thread, as I'm actually serious about booking this now. I found that Air France has award availability (expertflyer indicates 4 seats in "O" on the outbound, 2 on the return I want), and called Delta to check how many miles would be required. The agent said she doesn't see the availability I see, and said getting to PPT is near impossible with miles.
Has anyone successfully booked this trip before? The award search engine is (obviously) useless here. Is AF availability on expertflyer not indicative of the inventory released to DL customers? Any tips??
