I sat next to a NetJets pilot on a recent commercial flight and we chatted about how he usually flies on a day's notice to anywhere within his jet's range (but mostly the Caribbean & Mexico).

I've been thinking about what he said and now wish I had asked him one more question: how he deals with visa issues. A day's notice is not usually sufficient to secure a business visa to most countries. So, how do international pilots do it? Do they just perpetually renew multi-entry business visas to every country they could possibly fly to? I'd imagine this is easier for scheduled service since you can do your schedule & staffing plans well in advance, but juggling border formalities must be a huge headache for chartered & fractional pilots.

Anyone have any insight into this?
