If you know the latitude and longititude of your 2 cities you can use this site to get the distance between the two points.. it has a list of 326 cities that it already knows the details for... try it at:

Looks like the www.vsv site calculates using a spherical earth, so it can be off by 10-20 miles or so. For lots of purposes that's good enough, but if you want the actual correct distance you can get the airport lat-lons from airnav.com or worldaerodata.com and go to Ed Williams' ever-useful site http://www.best.com/~williams/gccalc.htm to get the distance.

Has anyone found a site that gives airport-to-airport distances directly on the GRS80/WGS84 spheroid-- i.e. without having to look up the lat-lons?

http://gc.kls2.com uses the Clarke 1866 spheroid, so its mileages are better than many, but they can still be off by a few miles.

http://www1.drive.net/evird.acgi$pass*42873027!_h-www.landings.com/_landings/pages/search/search_dist_apt.html apparently uses a spherical earth, as do most other sites.

If you find a possible site and want to test it, try HNL-RAR, which should come out 2542.3 nm, and LED-ANC, which should come out 3556.8 nm. Also, the equator to the 45th parallel should be 2691.655 nm, while 45 degrees to the pole is 2708.975.

I dont think anybody has posted this one yet, but its the one I use all the time. It will alsocalculate frequent flyer milage for the different airlines and membership levels, bonus miles etc.

Thanks for the suggestion-- I hadn't seen that one. Looks like they use a spherical earth too; they give 2940 miles for HNL-RAR (actual 2925.6 statute miles) and 4080 for ANC-LED (actual 4093.1).
