Using ITA as a guide, SCL-MAD on IB has YQ of $480 USD (ouch!)
SCL-LHR $263 USD, but also the LHR APD is another $200 odd I believe? So pretty comparable on price. Unsure how this actually relates to the real world.
EZE-MAD on IB is a bit more reasonable at $287.
So, fingers crossed, I'm going to try tomorrow to lock in the first half up to Europe:
kix-syd (stop) -scl-eze (stop) -mad-(bud or vie or fra or vie, stop) - doh - mel (stop) -kix
Ultimate destination in Europe is KTT, but I just don't have the miles spare
Another option was Mnl-hkg-syd-scl-eze-lhr-hel-sin-syd-mnl ....... but it seems HEL-SIN is near impossible to get.
Mnl-hkg-syd-scl-eze-mad-hel-doh-adl-mnl might be easier, and just sneaks under the miles.
Any sage words of advice? Any experience with taxes and surcharges ex-Japan vs ex-Philippines?
