Krakow, Poland (KRK) - Small airport, good transportation to the city (train every 15min thats 15min long) Lounge is real nice, with free booze, and PCs, printer, and sandwiches and other snacks. Quick checkin.

and Midway (MDW) I would say too as security is usually 10min long at most (usually 5min or less for me) and good food (Potbelly)
