I am almost positive the S family flew out and back to RSW. Not difficult at all to get a short notice flight during this low season time of the year from RSW to TWEED New Haven and back.
There is only one standard schedule flight with US AIRWAYS EXPRESS Dr S could have taken from CT via PHL/CLT to Fl, that would take her home by 10:30pm on that Sunday night, June 28th:

TWEED New Haven airport is only 11.5 miles from Ansonit CT, where she and her family stayed with AL:

TWEED New Haven only operates one airline, US AIRWAYS express:

From the airport to Jarvis it will take about 25 minutes (including traffic lights) during the night , straight via I75 or Corkscrew/ I75. We are looking at a distance of app. 17-19 miles, depending on how you go.
So yes, Dr S would be home by 10:30 exactly.
