Got this from the travel security service that David Neibling uses with Campus Crusade for Christ. Here is what it said about flights and evacuation:
The U.S. Air Force has provided air traffic control equipment to Toussaint Louverture International Airport (MTPP/PAP) to help land relief aircraft safely and reports indicate that 24 hour airport operations are now possible.
...Reports indicate that the U.S., Canadian, French and South Korean governments have begun evacuating some of their citizens. However, commercial flights remain canceled, and they are unlikely to resume for the foreseeable future.
