We had no issues with Asia travel (several wks after tsunami)
We saw no rev upgrades given on 4 flights.
DL does upgrade revs if coach is oversold until revs are accommodated. NR's get the leftover--if there's a big disparity, I doubt it's an issue. I had S4 with me and we got biz all 4 legs to BKK.
There can be a high no-show factor on some Asia flights from changing refundable tkts, etc.
What's your destination? What gateway is closest to you?
