United Airlines flights were grounded nationwide for about an hour Wednesday morning due to a computer issue. Passengers reported getting handwritten tickets, blank computer screens and long lines.
United blamed on a bad router for the travel headaches, the LA Times reports.
The airline said in a tweet that it "experienced a network connectivity issue." The Federal Aviation Administration cleared United to fly again by 10 a.m. ET.
