Flight operations are suspended at Houston's two major airports starting Monday night as a strong cold weather system moves through Southeast Texas.
The airports will shut down at midnight Monday into Tuesday morning, then officials will monitor the weather all day and will make a decision sometime on Tuesday about when and how to reopen (whether to reopen all at once or to lift restrictions slowly)
Houston Airport System Director of Aviation Jim Szczesniak said Sunday evening that travelers with existing travel plans will need to contact the airline from which tickets were purchased to find out about re-booking.
He added that travelers will need to refrain from driving to the airport during the flight suspension period.
"We've coordinated with our airline partners and for Tuesday the airport will be closed.
"The airlines have implemented their travel waiver programs, so you do have the ability to go to your airline and change your flights without change fees, so be sure to go to your airline to find out about that."
A reopening decision will be made on Tuesday, "and we see how the storm has impacted, then we'll get with the airlines and we'll then update what our plans are going forward for potentially Wednesday."
