Going to Asia in a few days and I have only flown on a 777 once. That was SQ from SIN-MNL earlier this year. I have flown the 747 many times, as recently as this summer. Having the choice of flying ATL-ICN n/s on the 777 or DTW-ICN (via NRT, and not minding the connection) which/what would be the most comfortable aircraft for this routing? Knowing the 747's probably won't be around too much longer (gasp) I thought I better fly on it while I can. Also, does DL upgrade non-wholly owned carriers for non-revs? That of course is a major factor.
