https://www.cbsnews.com/videos/delta-ceo-on-free-in-flight-messaging-puerto-rico-relief-challenges/The irony of this is that with the number of people trying to get to relatives on the main land, I'd think clogging chimerical flights with people who should have access to other means of air travel (like hitching a ride on a cargo plane) would be the greater injustice. Those few successful commercial flights are needed as much as incoming assistance for PR's citizens.
The short version: humanitarian aids (and cargo, I would guess) going in, no infrastructure to get people back. On another interview, FEMA AsstDir on CNN this morning said (sry, no link) is looking to bring back people with military cargo planes. Problem is configuration changes (aka where do you store the seats for the trip back in if you are bringing in cargo).
