For example, in 2003, a round trip across the Atlantic on the Concorde cost £8,000, equivalent to about $15,475 in 2017 U.S. dollars, almost twice the first-class ticket price on a Boeing 747.11 Once the attraction of novelty wore off, the airlines found it difficult to fill the seats, often flying at less than half capacity.12
Ooo! Thank you for that! Finding citations for certain statistics are hard to come by.
