There is currently one flight a day from XWA-MSP. It departs at 3:10pm and arrives in MSP at 4:48pm.
For whatever reason the flight is cancelled in advance for Thursday. It did operate today (Wednesday).
The challenge is there is currently only one flight a day on MSP-MCO and it departs MSP at 9:40am.
There is no ability to fly XWA-MSP-MCO on Delta without an overnight stay in Minneapolis.
This is a problem others are experience with such a limited, bare bones schedule and only one flight per day from many of these really small outstations.
Plausable Options that I see:
1) Drive to Minot, where Delta has a 6:28am departure to MSP that could connect on to the MSP-MCO flight
2) The only other flight out of Willston is a United flight at 9:18 am to DEN that appears to have a valid onward connection on DEN-MCO
3) Take the Delta flight XWA-MSP overnight in MSP then fly to MCO the next morning
