I'm flying end of December and they seem to have issues with icing? Is this something I should be worried about? Thanks.
The ATR icing problem was 25 years ago. I'm sure you'll make it safely by this point.
If you're on a US commercial airline, then you have less chance of dying on a flight than you do doing anything else you can imagine, including sleeping in your bed at night. (A 75-year lifespan spends about 750,000 man-hours in bed, with one death in those hours. The deaths-per-flight-hour rate for US airlines is between 1/10th and 1/100th of that.)
If the airplanes couldn't meet the safety standards of the FAA, they wouldn't be flying.

Remember that every single commercial aircraft flies every single day. Probably multiple flights per day. For most of these flights you're not on board, and don't care - but they still happen.
If an airliner crashes, it's headline news everywhere in the world. Thus we hear about pretty much every aircraft accident, no matter where it happens. I read about such things a couple of times per year - often a regional or commuter air line in some remote country. I've not read about major crashes in Europe this year.
Airline crashes simply doesn't happen, at least not in the western world. Whenever they happen they're basically a combination of multiple bad things at once, and more or less impossible to predict.
