Aviato

Aviato is basically a Kayak for people who've got better things to do than check JSX, Aero, Tradewind and Slate individually — it aggregates private and semi-private flight operators in one search so you're not opening four different tabs just to compare fares. The concept is stupidly simple, which is exactly why it works: private aviation is fragmented as hell and nobody wants to do that homework before a flight. The real test is whether the booking experience actually holds up, because aggregation only matters if the checkout doesn't become its own headache.
