We are planning a trip from Miami to Puerto Rico in January 2018 but we are concerned about safety as the flight path lies within the Bermuda Triangle.
What can you tell me about the safety of flights within this triangle?
The 'Bermuda Triangle' is an urban legend, nothing more. (just gooogle it)
In addition, the flight path is nowhere near the triangle, which is much further north. You don't need to be concerned at all.
According to the US Coast Guard, the Bermuda Triangle is not a real phenomenon. They claim that the agency "does not recognize the existence of the so-called Bermuda Triangle as a geographic area of specific hazard to ships or planes".
