edit If it's the evening TK flight you're on, you'll have to walk over to T1 Gate B1 (closer than the T3 bus gates) to get the bus. Will just take a few minutes.
Thank you! I did not realize the terminal transfer bus doesn't run until 11:30 (kind of shocking, but I'm sure there is a good reason). It was the morning flight I was eyeing. The evening one works as well, although I'd be losing a half a day of a short trip. I might take the time to get some deep dish pizza.
