Southwest expects normal Chicago Midway operations after harrowing Sunday

FILE Southwest Airlines cancelled more than 200 flights out of Midway International Airport Sunday

Hundreds of passengers were stranded at Midway Sunday, with deliveries of more de-icer not expected until Monday, according to the airline.

Flights departing and arriving from Chicago's O'Hare Airport didn't fare much better.

The carrier had encountered a similar issue before Christmas, when it was forced to cancel approximately 90 flights as harsh weather conditions prevented its de-icing crews from servicing its planes. The airline said flight 2123 was pushing back from the gate when the ground crew observed a possible fire near the rear exterior of the aircraft.

Flights coming in and out of Midway were canceled on Sunday after the airport ran low on de-icer fluid.

More than 250 cancellations occurred at the airport, with most being Southwest flights.

As of Monday morning, "Southwest has resumed operations at Chicago (Midway) and expects to operate a close to normal schedule", a spokesperson for the airline confirmed to Travel + Leisure. The day after Christmas, the airline cancelled nearly 90 flights because of delays over de-icing aircraft.

A winter storm that dumped about 9 inches of snow on the Chicago area by Friday evening was followed by another 3 inches of snowfall Saturday night into Sunday afternoon, according to the national weather service.
