I'm seeking to book a SkyTeam award to Bangkok. Am I correct that my long haul choices boil down to Delta, Korean Air and China Air? Of the three, which offers the best business product? First product? Any tips on booking?

From my review it appears that Korean Air probably has the best business product. I was further curious about possibly trying the A380. I"m looking a month out for availability and not finding much so booking tips would be great. Was using the Wandering Aramean's site for availability. Does anyone know if they loosen inventories prior to departure like Cathay does? I'd be booking with Skymiles.

Thanks.
