A computer glitch at a Kennedy Airport terminal that forced flight delays and a backlog of thousands of passengers waiting to be checked into their flights has been repaired, a Port Authority spokesman said Monday.

The breakdown at about 4 p.m. Sunday at Terminal 7, operated by British Airways, left thousands of passengers waiting to be checked into flights manually and forced airlines to scrap their standard check-in procedures, Port Authority spokesman Neal Buccino said. Workers had to instead issue handwritten boarding passes for Memorial Day weekend travelers.

Buccino said in an email early Monday morning that computer systems at the terminal were back to normal and that normal operations are expected Monday. He referred all other questions to British Airways.

A message to British Airways was not immediately returned Monday.

Sunday’s glitch affected only Terminal 7. British Airways also leases terminal space to other carriers, including Iberia, Qantas and Cathay Pacific airlines.

British Airways has been fielding passenger complaints of chaotic lines and long waits on Twitter, responding that “the delay was out of our control.”

The five other terminals at JFK were asked to accept inbound flights originally scheduled to arrive at Terminal 7, Buccino said Sunday.
