Heading down to SJO next week in A (First) to MIA and I (Business) to SJO, and hoping to catch an earlier (but same day) flight. Having only used the PLT same day standby domestically, I'm wondering if anyone has had experience with standby or confirmed flight changes to Central America? It seems that the elite same day benefits are only applicable on flights "within the U.S., Puerto Rico, U.S. Virgin Islands, Canada and international points in the Caribbean." I'd imagine that showing up to the Admirals Club and asking to get on an earlier flight might work, but hoping to see if any MP'ers have first hand experience with this situation. Thanks!
