For those not flying on AC at particular airports (i.e. unable to access the lounges), the MLL Wifi also leaks outside, so -- find a seat nearby, and lo and behold, free internet.

I still cannot understand why most airports don't just offer free internet. I am always thrilled when airports do - ABQ, PIT, SYR, PDX, etc etc etc. Makes connections so much more pleasant. (granted, I know it makes money, but I've never spent money at airports for the 2 hours of internet I need).
