"Our runways are open and we're ready when they are," Interim Director of Airports, Justine Ruff, said.
Ruff says workers have been treating the runways since Sunday night. There are different ways to know when the runways are ready for take-offs and landings.
"We have sensors built into the runway that will tell you what the temperature is on the surface. As soon as it hits 32 degrees you know it's going to freeze. If it hovers above that, you don't have to do anything. So you know exactly when you have to apply your de-icer," Ruff said.
Ruff says de-icer can be expensive. On Monday, they had one runway treated which kept the airport open for arrivals and departures. For passengers whose flights were canceled or delayed, it wasn't because of the conditions here but from other airports.
"Completely unexpected. I talked to my wife and her Grandmother and they told me not to worry about the weather. I get here and my flight is cancelled," Traveler, David Wild, said.
Wild is in town from California. He had to call friends in Monahans to come and pick him up. Wild will be back Tuesday morning to hopefully catch a flight back home. He says sticking around in the airport wasn't an option.
"It would be more fun if this was Las Vegas. I'd hit the slots or something," Wild said.
Harsh winter weather happens every year causing delays and cancellations. Airport officials say this year has been the worst.
"We usually have three or four snow/ice days a winter. This year, we've had more. What we had in early January was the worst I've seen continuously in the 24 years I've been here," Ruff said.
With temperatures remaining below freezing Monday night, more flight delays and cancellations are expected. The airport advises travelers to call the airlines for flight information.
