First of all, great find! How did you even "stumble upon" this fare??
I just put my ticket on hold through the AA.com site. I booked multi city for Nov. 20 - Nov. 28 for USD 1,603.
AMS-JFK
JFK-SCL
SCL-MIA
MIA-MAD (through JFK)
My only question is if I will be able to skip the first and last legs as I would be originating in the USA. Much easier for me to get an round trip award ticket to JFK as I am based out of the midwest. Does anyone know if this will be an issue?
Thanks in advance and again... great find!
