Anybody who wants to fly to DR would also have to consider if they would really want to under the new circumstances the country is under. And they would need to look at what their own country permits/recommends. If there are ferry flights now to the US will the US then permit their citizens traveling here with the risk of having to come and save them again.
As I have been told by a pilot, those ferry flights will be the last out of the DR, absent extraordinary circumstances.
On the flip side, the DR is arranging, or perhaps trying to arrange, to get some of its citizens who are stuck in the US....back to the DR.
In the, I am not sure who wins department, flights of Dominicans being deported from the US after having served their jail sentences.........are on hold.
Finally, as to when the airlines might begin again to fly to the DR..........AA has just announced no change or cancellation fees for those buying or already holding tickets through September 30. United has gone further, they are extending the same policy through the end of 2020. Read into it what you will.
