I'm guessing it was really cancelled inbound and they posted it late to their website. We haven't heard from them and I'm hoping they are making the rounds of other carriers to see who is flying North. I suggested they go South to Honduras for a couple of days. That option was probably the right one but they didn't take it.
You'd think they'd just up the schedule of all of their outbound flights and pack everyone on they can fit that want to go. Save people and equipment at the same time. Well, I suppose Belize City won't be getting hit as hard as SP and areas north. I can only guess at their logic.
