Frozen fuel lines forced cancellation of some O'Hare flights

CHICAGO - Frozen fuel lines at O'Hare International Airport forced American Airlines to cancel more than a dozen flights.

As temperatures again sank below zero, airline spokeswoman Leslie Scott says, the fuel system froze up around 5:30 p.m. Friday.

She says 16 of the airline's regional American Eagle flights were canceled. Other flights were delayed.

The airline put a backup plan in place and used tanker trucks to refuel planes at each gate.

WMAQ-TV reports that passengers had to endure long waits on planes that were held up on the tarmac.

By Saturday morning, the airline said the fuel lines were working normally again.
