Until more airlines start offering in-flight Internets… I treasure my time on a plane, as it mean I can actually write some draft, etc. Once there is Internet -- yes, I *could* always just turn off my Wifi / not sign up for the in-flight bits, but I'm not disciplined enough. I end up deciding I quickly need to look up some reference and then: http://xkcd.com/214/ W > > Lloyd Wood > http://sat-net.com/L.Wood/ > > > ________________________________________ > From: ietf-bounces@xxxxxxxx [ietf-bounces@xxxxxxxx] On Behalf Of Mark Nottingham [mnot@xxxxxxxx] > Sent: 31 May 2013 10:59 > To: ietf Discussion > Subject: [IETF] Time in the Air > > In an attempt to inject some data into the discussion, I wrote a bit of code that figures out how much time, given your home city, you would have spent in the air if you'd attended all IETF meetings since IETF74 (i.e., from 2009 onwards). > > The first column is the "home" airport. > > The second column is the great circle time between the home airport and the nearest large airport to the IETF meeting, hhh:mm. This doesn't count things like transit time, taxiing, takeoff and landing overhead, indirect routing, etc. As such, this is an ideal number; the only way to achieve anything close to it is to have a private jet (with exceptional range). > > The third column is the time (hhh:mm) using the shortest-time routing on a travel booking engine.
