The extreme cold is doing what snow did: Playing havoc with air travel. As of noon ..more than 35-hundred flights had been cancelled around the country .. many others are delayed. But .. not all of the problems can be blamed on Mother Nature. Channel 4's Ashley Harding joins us live from Jacksonville airport with an update on takeoffs and landings .. Ashley. 3 3 Well, we are lucky in the sense that JIA is more of an original destination hub, so there's really not a lot of people "stuck" here in between flights. But the last time I checked, we have _________ delays and we know of at least _______ cancellations. And for some people we spoke with, there's no telling if they'll get out tonight or tomorrow. 3 23-3048-551'12-1'19Places to go...people to see....and flights to catch....or not. "The original flight we had was at 11:37, which is now delayed for at least four hours. Probably more." TRACK Fredrik Roxenius is among the countless people dealing with flight delays at JIA. He and his family are trying to get home to Sweden, but their connecting flight to Newark is the problem. And there's no telling when they'll be able to leave."It's not that bad... yet. But I guess if we're stuck in Newark for a couple of days, then it will get serious. But...touch wood. So far, we're not there yet." TRACK Extreme cold temperatures are overwhelming several parts of the U-S, causing thousands of flight delays all over. We spoke with Debbie Jones, who works at JIA...and says when it comes delays, it's not all JUST about the bad weather."Crew availability, there could be a mechanical delay. So just because it's not necessarily a northern destination doesn't mean that there can't be some kind of a delay." "It's just a little crazy, a little hectic." TRACK Meg Redmond still waits for her flight to Nashville, but for her, the big concern is the 3 hour drive she'll have to make back home to Louisville, Kentucky. "They're saying wind chills are negative 20, negative 30 up in Kentucky. So, we'll see. Thankfully I don't think there's any snow up there, but, it'll be interesting." TRACK In the meantime, for these folks left hanging high, there's plenty of time for waiting around."Been to Starbucks, so that helps. We actually had some stuff with us because we thought this night be the situation." "It's weather. There's not much you can do, you just, wait it out." 3 And a big reminder tonight, you MUST check the status of your flight and also those of your family members. You can do that either through your airline or you can go to flyjax.com.Live from JIA, AH, CHANNEL 4,TLS.
