I recently found out that my AUS-DFW-MCO flight next month had a schedule change. Connection time in DFW went from 8:15a-9:45a to 8:15a-9:25a. Normally this would be a good thing and I wouldn't look further. However, I stumbled upon an ACT-DFW-MCO flight with better times that I would much rather have - for $40 less/ticket than I paid for the AUS flight. (ACT is hometown airport, very small so easy to get through, no parking fees, etc.) Is there any chance of leveraging the schedule change to change flights to ACT? This is all booked in Q.
