From Wikipedia:
Between 1984 and 1991, British Airways flew a thrice-weekly Concorde service between London and Miami, stopping at Washington’s Dulles International Airport.[117][118] Until 2003, Air France and British Airways continued to operate the New York services daily. Concorde routinely flew to Grantley Adams International Airport, Barbados, during the winter holiday season.[119] Air France also used Concorde on flights to Denpasar, Indonesia, from early 1988 into the 1990s, when the route to Denpasar was terminated and replaced by conventional services to Jakarta. The Jakarta route was considered for service by Concorde, but Jakarta's airport did not meet the requirements for the aircraft.

A quick look shows that, other than a British Airways plane being taken over In Iraq after the invasion of Kuwait, not much to work with as far as ships, planes or trains go. maybe 1991 or 1992 will have something better. Or if you could move your story up to 2000, you got the Concorde crash.
