### Around the world in (considerably less than) 80 hours

A thought experiment. I would need to go home and throw some stuff in a backpack, and get my passport, but this is doable. It was 2012 Sep 19 11:00am MDT as I searched.

Also as of 11:00am, this flight had a cost of $5,351.89. I couldn't swing that right now, and I have work to do for the next few days, but Phileas Fogg wouldn't have any such trouble. He had £20000 cash in his pocket, and this trip would cost about £55.16 There are probably possible trips with tighter connections. There are surely trips that are cheaper with a longer lead time -- I found one in January for ~$3500.

This trip is definitely around the world. It crosses all the meridians. But, it is only 32833km as the crow flies. I have heard that a trip around the world must cover a distance longer than one of the tropic circles (36787km). This trip doesn't cut it if it follows the great circle route, but if the actual routing is 10% inefficient then it counts.
