I know we've covered similar topics, but I don't think we've covered this exact one.

Here's my situation: I would like to book three coach award seats from MCI to Northern California. I have enough miles to claim the awards on any of the Big Six. I am both date- and airport-flexible, but am looking for a way to quickly and easily modify my search if a date/airport is totally unavailable.

Right now, the only way I can think of to find availability is by going to six airline websites and navigating through six not-so-user-friendly search processes.

Question: is there a better way to more quickly research this - maybe via ITN or something similar? (My gut feel is that ITN doesn't show all fare classes for all flights.)
