Thank you for the responses. Travel not scheduled until end of June. I try to have contingency plans in place so that I'm not posting to FT from the airport on day of departure moaning about how the airline didn't reaccommodate me for a same day arrival.

So no one thinks DL will re-book if travel involves segment(s) on CI or KE? BR 52 IAH-TPE non-stop would be ideal, but I don't see DL doing that.
