When returning from holiday, one starts to think of holidays

By 'south of the Rio Grande', I mean 'into Mexico' rather than 'anywhere south of 31N' - I thought this was standard usage, but various of my friends in Cambridge interpreted it the other way.

Hmmm, actualy, I'm not sure whether the LHR-SFO great circle crosses the arctic circle or not. I fed it to a great circle plotter and it looked close - however the map didn't have the arctic circle marked on it.

Not sure either, I flew LHR-LAX out and SFO-LHR back and I'm not sure we went *that* far north ... but I'm sure my SAS flight to Japan that went north of Russia must have crossed!

Transatlantic flights can depart from great circle quite a lot, though - further North (or a lot further South) when going Westwards, usually (it depends where the jet stream is - going West you want to avoid it). I flew LHR-LAX recently and probably just avoided the Arctic Circle, but went over the tip of Greenland.
