No, Concorde was a money-loser from day one.
The governments of Britain & France literally gave the airplanes to British Airways and Air France. The airlines did not have to pay for them; just the cost of operating and maintaining them, which even still did not result in a worthwhile profit. Basically, it was cold-war nationalistic prestige purchase. The net result was average British & French taxpayers made to pay for wealthy celebrities, businesspeople and other 1%-ers to fly trans-Atlantic at great speed. (It didn't have the range to fly any other worthwhile route)
If all airlines didn't have to finance hundreds-of-millions of dollars it cost to buy each plane they operate, they'd all be fabulously profitable.
