MIAMI – As a major snowstorm grips southern US states, many airports have been forced to cancel flights or completely close their airfields. 

These airports affected include but are not limited to Dallas Fort Worth Airport (DFW), San Antonio Airport (SAT), Austin Airport (AUS), Houston Intercontinental Airport (IAH), Houston Hobby Airport (HOU), and Baton Rouge Metropolitan Airport (BTR).

According to, at least 853 flights were canceled from DFW. 

Record-low Temperatures

The region saw record breaking low temperatures with Austin and San Antonio, for the first time since 1989, seeing single digit temperatures. 

In addition to the low temperatures and snow that hit Texas, a series of power outages have forced many residents to practice critical power conservation methods. The most affected airlines are American Airlines (AA) with a hub at DFW, United Airlines (UA) at IAH, and Southwest Airlines (WN) at HOU. 

At the time of writing, IAH plans to remain closed until 1 pm tomorrow. HOU will remain closed until noon tomorrow. 

Chemical Treatment at Airports

Crews at the airports will need to apply chemical treatments to melt buildings of ice and plow snow to make conditions safe enough for aircraft to perform flight operations. 

Although DFW has kept flights departing and arriving, the airport is asking passengers to make sure that their flights are still scheduled before heading to the airport. 

The FAA has imposed the Traffic Management Program at DFW, which is causing delays upwards of an hour and a half for each flight.
