If I am not mistaken, BIH operates up to 9 flights a day to the islands, so that's a daily capacity of almost 250 seats. Don't know what the load factors are, but to make up for that shortfall in capacity, Skybus would need to operate something like two additional Twin Otters from NQY or dozens of Islander flights from St. Just. Or is the general belief that passengers will opt for the vomit comet, i.e. take the ship?
To me, it sounds a bit more like pressuring someone as the islands obviously cannot operate without a replacement for the transport capacity BIH has provided for decades.
