I fly LAX-BKK r/t a lot. Every trip in the past 2 years for me has always been LAX-NRT on one flight number and NRT-BKK on a separate flight number. My trip next month seems to be the same route but now 1 flight number all the way LAX-BKK. I always use SWU on these flights and they always drop at different dates on a per segment basis...

My question is, are you going to get screwed on a multi-segment but one flight number with the upgrade clearing? Anyone have any experience with this...

Not worried, just more curious
