Stranded passengers wait in line at the Southwest ticket counter at the Salt Lake City Airport Thursday, Jan. 24, 2013. The Salt Lake City International Airport was closed due to icy conditions. A Frontier airplane slid on the runway during landing Thursday morning, but nobody was injured. Five flights were canceled and 15 other planes were forced to return to their gates when the runway was closed. The airport is a hub for Delta Airlines. Freezing rain has also caused dozens of accidents on roadways around Salt Lake City this morning.  (AP Photo/Rick Bowmer)
