This is much like Hawaii would be under the Green New Deal. The tourism industry would be non existent without airlines flying people there and getting supplies from the mainland via windjammers would not be too efficient.
I read that in general....tourism income for the Island is around 21 to 23 percent. If you yank out flights in general....to those who own condos and stay there six to eight weeks out of the year...it probably adds another 3 to 5 percent on top of that amount.
I’m guessing if you tasked the hotel chains and local tourist ‘handlers’....they are in dire straits, and some already have bankruptcy lawyers working on drafts. If you shut down 15 to 20 percent of the island revenue ‘machines’....ask the state where income tax and sales tax revenue will come from.
