LONDON - For more than 30 years, Ralph Kirshbaum bought two airline tickets for his trips. The world-renowned American musician, who lives in England, bought one seat for himself, and the other for his strong, silent companion - a priceless 250-year-old Montagnana cello.
But British authorities say Mr. Kirshbaum must now sit alone. Since police broke up an alleged plot to blow up transatlantic flights last month, restrictions have been placed on travelers: Nothing larger than a laptop bag can be carried into airplane cabins. But cellists, violinists, and French horn players are loath to consign their instruments, often antiquities worth millions of dollars, to cavalier baggage handlers and the rough-and-tumble conditions of the aircraft hold.
As a result, hundreds of musicians in Britain are complaining that the measures designed to thwart terrorists are in fact punishing virtuosos with nothing more malicious in mind than a Saint-Saëns solo.
The performers, who shuttle around the world to concerts, rehearsals, and festivals with ancient instruments in tow, are warning that their performances - and even livelihoods - are in jeopardy because the new rules make international travel almost impossible.
