Actually booking a trip is kind of exciting, lots of things flash and whiz around on the screen, messages appear and disappear, then it tells you to call an agent
I have found it good for playing with fares though. On this GLA trip, I found that depending which code-share carrier I chose for LHR-GLA (all the same BD flight of course) the fare varied vastly. I ended up with one leg as BD and the other as SK and saved over a hundred bucks.
