So, I have a trade show literally across the street from O'Hare. Tuesday morning arrival, Wednesday noonish departure. What's the chances of being able to fly in there in a piston single? VFR? IFR? @Radar Contact , should I just drive around the lake as this is not going to happen? Signature says their fees are are $54 (not including parking or Chicago fees) so not horrible. Edit: Signature fees, not so bad. City of Chicago fees, bring lube.
