It's a huge enabler - right now, flying to see my family in Brazil is a huge PITA - two airports and 12+ hours in the air. It's less horrid in business class, but still something I tend not to do more than once a year.

If I had a 5-hour direct flight, it'd be a no-brainer.

Maybe I'm just more accustomed to long flights, but a 12-hour non-stop flight in business class if I'm not really thinking about the cost much just isn't a material inhibitor for me. (And whether there are non-stop flights is a separate issue.) Certainly shaving off 6 hours of flight time wouldn't really affect my calculus much, if at all.

If I have a 2 hour flight then no, it isn't. If I have a 12 hour flight then it's worth more.
