An airplane operated by Southwest Airlines slid off the runway at Chicago's Midway Airport after landing, the airline confirmed Tuesday afternoon.
The plane, en route from Denver, Colo., had landed in rainy conditions, Southwest said. The airline added that no one was hurt in the incident.
"The passengers have been safely deplaned from the aircraft using air stairs and have been bused to the terminal," Southwest said in a statement. "Southwest officials will be working with passengers to get them to their final destinations."
The plane was a Boeing 737. At the beginning of this month, another Southwest 737 had to make an emergency landing in Arizona after a hole opened up in its fuselage. That incident led the airline to inspect almost 80 of its 737 fleet.
There was no confirmation Tuesday if the Midway incident was equipment-related or strictly due to weather conditions.
