work being the constant flow that it is, I've got to restate my question.

I'm now going to be coming into BUD from elsewhere - work will pay, I've got no problem walking away from the value of the unused 1st 1/2 of the ticket. Existing PNR is Y, my new way into BUD will be J.

I will split the PNR so my gf and I are separate, and she'll use her reservation as it was booked.

My reservation:
What are my options and how can I avoid the most pain? I still need to use the return flight bud-ams-sea but will not be using the outbound sea-ams-bud flights. I don't want the reservation cancelled because I failed to use the 1st half. I also don't want to pay a $XXX change fee to not use half of a ticket.

I don't know yet what carrier I'll be on, but it won't be delta (coming in from asia) - could possibly be AF or KL but unlikely due to their schedules. Taking delta the 'wrong way' asia-sea-ams-bud is not an option as I've got a meeting till late on a friday in asia and have to be in bud at 4pm on saturday...

what say you fine folks?
