1. You can get the "elite seats" only if you're an elite on Flying Blue, or other other Skyteam airlines' FF programs. You may be lucky this time. Elite status differ from airline to airline, but most require 25,000 EQM ("elite qualifying miles") in the previous calender year. Maybe you are one, maybe not.
2. CO has menus on their non-stop trans-Pacific flights from the US to NRT, PEK and HKG. Not on trans-Atlantic ones or domestics.
3. "Legacy airlines" in the US mean those that are not the new low-cost low-fare ones. AA, US, DL, NW, CO and USAir are considered "legacy".
4. AVOD on NW's 330 are provided in all seats.
