I'm planning to do my first mileage run this Tuesday on Southwest (Nov 18). DTW-MDW-CMH-MDW-IND-MDW-DTW. 18 RR credits.
I chose CMH and IND because I've never flown to/from either airport before (and because they were both $39 from MDW). I won't have enough time to see the cities themselves, but I'll bring a good book and explore the terminals.
Any suggestions on what to see or where to eat in CMH and IND?
