It’s interesting in its own right, to be sure. But for me it’s a useful tool in coming up with award itineraries. Say, for instance, that I’m trying to book a premium class award with United miles and I’d like to include a transpacific segment on Signapore airlines. I may already know that Singapore flies from LAX to Tokyo, Tapei, and Singapore. And from San Francisco to Seoul and Hong Kong. But I could easily have forgotten the option of flying Vancouver to Seoul.
Admittedly for the true airline geeks among us.
