Yeah, I was interested until I found that part.

I think for most people, if they could afford 4 months off work then they wouldn't be too concerned about finding the cheapest possible flights.

It's still interesting in a theoretical way, but far less useful than the headline makes it sound.

At least here in the UK (I know slightly less so in the US, so your mileage may vary) it's extremely common for students who are either between high school / university or just graduated to take a 'gap year', or some other period of time to travel. For them price is clearly a very important factor, and the four months isn't a huge problem!

I'm American and I just got back from 5 weeks backpacking in Southeast Asia. I through my trip was long until I met legions of Brits on gap years...
