Keno is correct. I was only providing an example of a routing I knew from memory to be longer than LHR
, not trying to establish that GIG
was the longest of all for the same flight number/same metal.
The earlier example I gave of the NW
routing, same metal, not necessarily on the same flight number, is the longest for that category.
P.S. If you haven't been to the Great Circle Mapper site yet, it's quite handy, and you can display the distance in mi/km/nm as you desire.
