I don't fly very often, so I don't know how an airline would handle this situation. I want to fly to Cincinnati next week. The flights on the airline that I want to use are higher than I want to pay, so I did a search on nearby airports. I can fly to nearby Dayton for $200 less on a flight that connects through Cincinnati!! So I want to stay in Cincinnati, since that is my final destination. I don't think they could stop me from doing that.

But would my return trip be affected? I'd obviously have to fly from Dayton on the return leg (I think they would cancel my seat if I didn't get on in Dayton, ie. I couldn't just catch the 2nd leg of my trip in Cincinnati on the way home).

Any advice or thoughts? I'd have to just bring carry-on luggage. Anything else I haven't thought of?
