It's a bit unusual to skip such a long haul, though. If I may ask - are you by any chance a professional swimmer, or are you planning on hitching a ride with the anti-whalers?

lovely. that puts the kibosh on the whole plan. what if i check in and receive both boarding passes, but don't board the plane? EDIT: NEvermind you said "don't get on the flight". Ugh.
haha, no - we want to also go to Tahiti, Easter Island, and through south america before coming back up through Miami. Trying to combine our BA miles into this trip as well. Would do revenue, NRT-PPT-IPC, then rewards the rest of the way. Can't figure out a way to do that or get close on *A. And now we'd essentially be throwing the rest of the ticket out if it invalidates ORD-YWG.
Hrrrmp. Advice? Outside of 'well then don't go to Tahiti and south america?'
