How else can travel insurance help me when my flight is cancelled or delayed due to winter storms?  Most insurance plans available through Travel Guard come with valuable assistance services. This means if your flight is delayed or cancelled due to severe winter weather, we will work with the airlines on your behalf to book a new flight and get you where you need to be.

If a severe winter weather warning or watch is issued that may impact my travel plans, up to what point can I still purchase travel insurance?
Insurance must be purchased 24 hours prior to when the severe winter storm warning or watch is issued. Once the severe winter weather warning or watch has been forecast, Trip Cancellation and Interruption losses resulting from the winter storm are excluded from the coverage of the policy.

As you can see with the answer to that last question, the best thing to do when traveling during the winter months and either leaving or traveling to (or through) a destination that may have a winter storm, is to purchase your insurance beforehand.  If you can predict 24 hours prior to a storm ever happening then I am just going to tell you that you need to apply for the position of your local weatherman... I don't know about yours but mine is never that accurate!!
