I had originally thought I needed ~16,000 miles:

...but I'm unexpectedly on my way to Tokyo this weekend so I'm a lot closer than I thought.

Appreciate any ideas on getting my last 6,044 from SFO (or OAK or SJC) to get to 1K. I'm way over on PQD, so just need the miles. Can fly any day after Christmas and return anytime one or before the 31st.

Still looking like SFO-EWR-STI is a good bet @ $681. Over 8,000 miles. Would love to find something closer to $500, if anyone has other ideas.

Thanks in advance! Love this forum...
