Several flights for British Airways scheduled to depart from the United States to London were delayed on Tuesday following a technical issue.
The airline said in a statement that it has resolved an issue that affected some long-haul flight planning systems overnight, causing delays in the schedule.
“We’re sorry for the disruption caused to our customers’ travel plans,” it said.
The airline said the problem was not a safety issue, and short-haul flights and flights that already departed were not affected.
The Guardian reported that delays occurred in multiple cities, including New York, Miami and Denver.
NPR reported that 14 flights from John F. Kennedy International Airport in New York City were delayed, and three flights were delayed from both Miami and Los Angeles.
The delays also appear to have affected some flights originating outside the U.S., as British model and actress Elizabeth Hurley tweeted that she was stranded at an airport in Antigua after her flight was delayed 20 hours.
BBC reported that the issue also affected flights departing from Canada and Mexico.
