Take a look at FlightStats Airport Delays map — it’s shimmering with red lights — which mean, major delays at Chicago’s O’Hare and Midway, and in Cincinnati and Memphis — with more delays in Houston’s George Bush and Kansas City, St. Louis, and Little Rock.

Feeling secure because you’re not traveling in or out of any of those airports today? Well, don’t forget — the plane you’re scheduled to fly on may be coming from one of those snowed-in or icy cities. In any case, our number one tips is check with your airline before you leave the house! And here are some other tips for travelers in lousy weather:

1. Batteries: Cell phone batteries should be full and your charger on you (not in a checked-bag)

2. Phone Numbers: Add your airline’s number to your cell, and the number of other airlines that fly to your destination. If you’re in a long line to change a flight, you’ll want to be on the phone, too (you might reach help faster)

3. Follow Twitter: Airlines are big on social media, and may tweet info on cancellations and delays faster than websites

4. Food: Bring some from home or stop on the way to the airport — airport restaurants may close early (or not open at all)

5. Stay calm: This is especially true when going through security; everyone’s on edge now, and any deviation from the rules could land you in real trouble (or at least delay you further)
