Yes, I am on the flight that has the 3 hr 45 minute layover in PDX. I was considering standing by for an earlier flight that same day so that I could spend the day in Portland before heading on to ANC. I believe I can choose to only standby for the first flight, and not the second? Any one have experience with this? Otherwise, I don't mind getting to ANC earlier... 1:30 am arrival in ANC was a little late for my taste anyhow
