I am not sure this is going to fly. (pun intended)

The aircraft in the plan is the 85 to 100 passenger Avro RJ. The RJ series ended production 15 years ago. They were intended for feeder route into urban airports with short runways and noise restrictions. When they were built that required 4 engines which means higher operating cost; high fuel consumption and maintenance. Maximum range is MIA/EIS at best. Their only attraction is that the older ones are cheap to lease which balances most of the higher operating cost.

While the scale of the tourism market of Bermuda and the BVI is remarkably similar, it is impossible to compare air service of Tortola with Bermuda. First off the airport was built by the US military as Kindley AFB/NAS Bermuda and maintained by the USAF until 1995. The only capital investment Bermuda made was in the terminal building. The debt service alone for the Beef Island extension will be almost $1 million per month. If total deplaning doubled over the 87,000 level before AE pulled out landing fees would have to average $70 per arrival just to service the mortgage. Add to that departure and security fees and you are bumping into $100 before any actual airfare. The STT route will always remain the least expensive route. The ferry service is the weak link.

Bermuda cannot be reached by ferry so all of the 224,000 overnight visitors in 2014 came by air. In contrast, in 2014 approximately 170,000 BVI visitors came by ferry. Simple logic shound indicate where any government investment should be made.
