1) If I take flight 01 IAH - GUM leaving IAH on 12/31, but arriving GUM 1/01 are the miles posted on the 2007 or 2008 ledger?
2) If I do this round trip and (try to) upgrade using miles, does CO count this as two legs, or four since it stops in HNL? Will I be charged 50,000 miles, or 100,000?

Thanks,
Scott
