I'm using my AA miles for my winter trip. They've changed their mileage amount it appears - now something like 75K to fly first rountrip SFO/Jamaica. And that's for the Plan AAhead miles. Last year I booked 3.5 months out, got seats but not my preferred route (got SFO-JFK-MBJ as opposed to SFO-MIA-MBJ). This year I plan on booking 4.5 months out and I'm nervous. Good thing I'm flexible with dates.
