This is interesting (especially since it appears to expose gate planning at least 36 hours in advance). However as noted it doesn't really take you through the true steps for a connection. Also on a C Gates to A Gates transfer it sends me on the train and then down to level -4 and up to level 2 for no reason (presumably it's crossing me from the arrivals to departures streams (illegally) while I'm down there..
The Gate info is nice but otherwise is a bit worse than useless because it doesn't show people the route they'll actually take.
