SAN JOSE, Calif.—Officials say a failed joint appears to blame for a water leak that flooded parts of a terminal at Mineta San Jose International Airport, leading to flight delays and even cancellations.

Terminal A was fully up and running again on Tuesday morning, a day after the leak flooded the baggage claim and security areas. Passengers were checked in at airline counters, but then taken to Terminal B on shuttle buses for security screening.

Airport spokeswoman Rosemary Barnes says several flights were delayed and a few cancelled. The terminal serves carriers, including American, Delta, JetBlue, United, U.S. Airways, Virgin American and Volaris.
