From looking at all the proposed/reserved itineraries (thanks to all!), it seems that flying through Miami is almost mandatory (presumably because of that Managua Miami segment)...has anyone looked at a strategy that originates in Houston or San Francisco/Los Angeles?
I guess the answer could be to just buy an open jaw on CO into and out of Central/South America and aim only for the 500K bonus. I will be in SFO and/or IAH at the beginning of March and wouldn't mind making a run myself. Thanks...
