Firstly, to teriyaki and Johnny, thanks for that feedback.


Johnny, interesting about the relative lack of Asia Pacific traffic from SEA-TAC compared to YVR.

On Another topic it was in the wind that KAL was thinking of doing
a Seoul - YVR- Lima tryout.
Hope it happens, hope it works.
OK; the tangent. Taking PAL as an example going from Manila to Lima:
May I present Exhibit A: Manila - Lima nonstop:

And now Exhibit B, Manila to Lima via YVR:

The court may note that while the YVR routing is while the Vancouver routing is 424 miles longer, this routing might prove more profitable in yield
Also of interest is Manila - Sao Paulo
Nonstop:

Via Jo'burg:

ok this is shorter, but is there enough O/D and connecting traffic to warrant it?
Is there a market there or elsewhere en route going east?
PAL (among others) have large markets in North America, and as Johnny, pointed out,
was surprised at the size of the Vancouver - Brazil market.
Oh, and as a last word, whereas most Asia - Brazil flights are shorter
through YYZ than YVR (except Lima): the distances of both city pairs is interesting to note here;
through YYZ, still shorter than via Vancouver:

from Vancouver:

:total distance, Vancouver loses by only 127 miles. The 8219 miles to YYZ would necessitate a 787, and that's unlikely given the cuts PAL already made there.
It seems Vancouver might have a chance at becoming a South America hinge after all.
