Flyertalk posts dissuaded me from flying the Concorde. I opted to splurge my miles for a First Class ticket from the USA to Australia via Europe and Asia for 150,000 miles. As I recall, the Concorde was 125,000 miles for NYC-LON. I thoroughly enjoyed my 70 hours of First Class travel and First Class lounges in London, Singapore, and Sydney and I felt that was a much better use of miles than a 4-hour trans-Atlantic flight.
