When I read the press release, I was convinced that DL had, thru some sort of contest, permitted the airliners.net crowd to plan the next new route.
Let's fly a 757 almost as far as it can fly, and then, before it runs out of gas, we'll stop at SID to refuel, before continuing on to Liberia. And then we'll do the same thing in reverse on the way back.
DL is certainly thinking outside the box.
