So I'm connecting through ORD to MKE for the last leg of my trip, but actually need to be in Chicago that day (I booked last August as roundtrip through MKE). I won't have any checked luggage, but what is the best way to handle the situation? Do I tell them at check-in, go to the gate at ORD (I have almost 2 hours so I can't imagine the GA would be working on the flight yet), or what? I'd hate to have them paging me, or delay the flight in any way, but I'd also hate to get in trouble at check-in.
Thanks for the help!
