The New York Philharmonic has yet again canceled a proposed trip to Cuba, and this time it may be for keeps. The orchestra was tentatively planning to go in June, but no charter planes big enough to take it were available, said the Philharmonic spokesman, Eric Latzky. In addition, the school year will have ended, making it too difficult to gather children for a planned youth concert, he said.

“I think the Philharmonic may go to Cuba some day but certainly not in the foreseeable future,” Mr. Latzky said. The Philharmonic was forced to cancel a trip last year after the United States Treasury Department declined to allow orchestra patrons to go along. It later granted a license when the Philharmonic designated the patrons as docents for the educational concert, putting them in the realm of what United States sanctions permit for visitors to Cuba.
