Hurricane Sandy is forcing airlines to reschedule and cancel flights. JetBlue, US Airways, Hawaiian Airlines and Spirit Airlines are offering waivers to customers who wish to reschedule their flights without paying the typical fee of up to $150. The offers cover passengers flying just about anywhere from Hawaii to New Hampshire, and even Latin America. Some flights in and out of Florida and the Caribbean already have been cancelled. Check with your airline. I’m due to fly out of LaGuardia on Tuesday — and have my fingers crossed.
