I would like to redeem miles using the Citibank reduced mileage awards to get to Dallas but it is not offered as a destination. Instead they have Waco, Killeen, Longview, College station, etc... It seems that to get in/out these places, the flight has to connect in Dallas. If I use miles to book a ticket to say....Waco , can I get off the flight in Dallas and check in at DFW? Will they allow me to do this?
