" 100+ seat jets and 300 plus miles is the secret of airline survival"

True...
Q: but what airline can fill 100 seats from a US gateway to EIS?
A: None.
Except from MIA. Maybe 1 r/t per day, not 2x

BVI does not have enough beds to put heads, or berths on boats, to fill those seats on the aisles, or faces in the windows of those jets.
