More likely than you think - for Europeans our winter temps are very mild. And they get a lot more bang for their buck on our beach verses South Beach, etc. And Europeans are not necessarily snowbirds - France, for example, celebrates their "summer break" in August and for an entire month. If you go to Paris in August, you'll find it feels empty, other than the tourists. In October, schools are let out for a few weeks and families head out - perfect weather in our area for those Europeans who can't take the August heat. Believe it or not, the Panhandle doesn't have a "redneck" reputation in France. Most of them haven't even heard of our beach - but they will. I think of Field of Dreams when I think of the new airport - build it and they will come!
If airlines thought direct flights to the panhandle would be profitable, they would already be flying into Pensacola or maybe Ft. Walton. Either place can handle the big jets. PCB is dreaming if they think direct flights from Europe are a possibility. Field of Dreams was a fantasy movie--just like direct flights into PCB from Europe are a fantasy.
In a couple of years when the airport is complete, let's check back on this thread to see the true outcome versus our current speculation.
