circle pacific - official mileage calculation
tried to search but couldn't find a discussion on this before...
any easy way to find the most authoritative answer to the total flight distances that's used in deciding 22k vs 26k? because, I tried the following itinerary, in all mileage calculators I found online, it's like ~15-20 miles below 22k...but my agent said it's actually 22,012.
HKG-NRT-LAX-SEA-PHX-TUS-LAX-SYD-HKG
I'm ok to change it a bit to fit under 22k but just because my agent does not always have the right answers to such more tricky FFP/airline questions...just want to make sure they're indeed correct. I'm ok if the official / authoritative distances used are somewhat different, but just want to see if there's a way for me to double check myself (besides calling up the airlines which might not be straightforward in finding the right ones who can answer the question etc).
thanks a lot !!

Your agent is right.

I think that you would be better off calling the airline which is issuing your ticket to be certain. I regularly find that EF has different mileage numbers from those on MileCalc.

Because, MileCalc uses Great Circle distance (probably).
EF shows TPM(Ticketed Point Mileage) that is used for air fare calculation.
For example, TPM for TYO-OSA is 280 miles.
This distance is applied for all combinations of TYO-OSA (NRT-ITM, NRT-KIX, HND-ITM, HND-KIX).
Another example is LON-NYC (3457 TPM).
JFK-LHR is 3451, EWR-LGW is 3483 (Great Circle).
