I'm flying in and out of ORD tomorrow. The first leg is AE and arrives at G18, the far end gate and I will be going to the Flagship Lounge at K18 . Although not officially disabled it will be a long haul for me as I recently had foot problems.

How can I get a ride on one of the electric carts? Would it be best to ask at check-in in Austin or talk to the agent at G18 when I arrive at ORD?
