Something Wierd About SXM

Mon Nov 10, 2003 5:02 pm

I was browsing the United timetable and came across this....

They list flights to SXM through charlotte and Philadelphia (code share). The posted mileage from Charlotte to SXM is 1,615 and from PHL - SXM is 1,675. That is 60 miles difference! But Philadelphia is 448 miles further from Charlotte (flight mileage, not driving miles) so where the heck do they get 60 miles difference???????????

Are they trying to screw the frequent fliers? PHL - SXM should be much more.

I don't understand that.

This is what SABRE says for the distance on these flights....

US Flight 877 18DEC CLT - SXM - 1614 miles
US Flight 1465 18DEC PHL - SXM - 1674 miles

This is what the Great Cirle Mapper says.....

CLT - SXM - 1612 miles
PHL - SXM - 1670 miles


Can't forget that curvature of the earth thing.....  Smile

well, i just checked it on my MS map and very similar.....wow, that one really threw me! I never thought that just because one destination is much further beyond a second destination that the further one is a shorter distance than if you flew between the two...

Don't forget that a) Charlotte is not on the Atlantic coast, but rather quite a bit inland, and b) The curvature of the Atlantic coast causes North Carolina to more western than Pennsylvania (which is why New England-Florida flights often fly overwater).

So even without looking at the earth's curvature, the lines connecting PHL and CLT with SXM are similar lengths.
