After looking at that website, I'm thinking you might want to follow the advice on this board and call the airline ASAP.

I grow suspicious when I put in my citypair, see some very irresistable fares, and but then cannot actually select flights and look at real itins/fares without contacting the agency.

For MCI-Tokyo, they show me $449 R/T, but they'd like to talk about it offline, if you know what I mean.
