|Subject: Re: Connecting Flight Question|
Because fare structures are so weird, travelers do what you're going to do all the time.
DO NOT SAY A WORD to the FA's! What you're doing is avoiding paying the fare the airlines think you should pay to your destination by cheating. An airline ticket is a legal contract between you & the airline. You agreed to pay $XX for travel to Dayton, not to Cincinnati; the airline agreed to carry you from origin to Dayton, not Cincinnati.
So here's the risk: when you don't show up for your connecting flight from Cincinnati to Dayton, the airline can & indeed may cancel your return trip. If you're only going one way, no problem. I did hear of a traveler who was contacted by the airline to pay the difference in price between the Cincinnati fare & the Dayton fare on a one-way trip, but I believe that happened because he was a frequent flyer & some busybody happened to notice his ticketed vs actual travel destinations when he was inquiring about a free ticket.
If you are going roundtrip, & the airline has cancelled your return, when you show up for your homebound flight, they may charge you the full coach fare for the trip. That's the risk. And because you have broken your contract with the airline by not continuing to your ticketed destination on the beginning of your trip, you have no recourse.
