If you’ve flown more than twice in your life, you’ve probably spent more than a few uncomfortable hours stuck in airport chairs (or on the floor) waiting for a long-delayed flight to get back on track. What you wouldn’t have given for just a few square feet of space to lie down and get away from your fellow disgruntled travelers.
Somehow it’s not surprising that Japan has been doing this for years. (Why do they get all the cool stuff first?) I may go back to my college strategy of bumping flights every Thanksgiving, to get a free ticket for December.
