Detroit Metro airport reopens after a 14 hour closure.
But the airport was not fully operational at first.
Travelers will face delays today as flights struggle to get back on schedule. 2 of the 4 primary runways were open at first.
Some of the passengers were stuck for hours on planes at the time the airport was closed, at 8 pm, when sleet diluted the de-icing fluid used on the runways and taxiways.
The average delay was 5 hours, according to the FAA.
Some flights were canceled.
