It would have worked for me while I was still working (till mid-2016). At any rate, after cancelling my planned USA visit, I only flew two domestic flights (HER-ATH-HER) during the past 10 months. I am now glad to be relying on my old car and ferryboats for my short trips on Crete and our annual looong vacation, also because we can take along our dogs. And, as an extra perk, I got to know places in (continental) Greece that I had previously only seen from the plane, but never realized how amazingly beautiful they are...
