One of my more recent trips to the BVI, I took AA out of JFK using a 757. We hit some geese and damaged the plane, so back to JFK. You would think AA would have a spare 757 at JFK but no we had to wait for a flight from Spain to come in, a 6 hour delay. So just because an airline has hundreds of planes does not mean you have spare planes. BVI airways could always fly one of their spare planes to Miami to fly passengers to the BVI if they had a problem.
Give them a chance to provide service before you bash them.
Too much negativity.
