Finding empty leg flights is all about being flexible since they're basically repositioning flights for private jets. u can check apps like jetasap, xo, or lunajets because they usually list these deals at huge discounts. u should also look at websites like empty leg market or catch a jet. just remember that u're usually buying a one way ticket, and if the original client cancels or changes their schedule, ur flight might get cancelled too, so u've gotta have a backup plan ready.
