Some computer issues at San Francisco International Airport are causing delays to departure flights, authorities said Wednesday night.

According to the duty manager at SFO, the issues impacted some ticket counters, meaning that some of the computers were not being used in the terminal. This has resulted in up to 14 departure flights with delays ranging from 5 minutes to an hour.

Authorities said these delays are mainly impacting the international terminal.

The cause of the issues is unknown, but authorities said a team is looking into the computers.
