It's possible. Looks around to be around 600 miles/9 hours which is plenty of time to get it to the hub which is in Dundalk I believe.Maybe by truck instead?
EDIT: My money is on that Southwest flight. The departure time matches UPS to the minute.
EDIT 2: Gate time was 12:40 with 6 mins taxi time which is 12:46 so who knows.
I just like following the flights. I know it will be at my door step tomorrow morning.
