Due to the draconian measures instigated at US airports & on US carriers I am considering rerouting my in progress LONE4 to avoid the US.

Present itinerary is: LHR-OSL on BA (flown)//NRT-DEL on JAL (flown)//SIN-PER onQF//MEL-AKL onQF-SYD onQF-HNL on QF-LAX on AA//SEA-ORD on AA-YYZ on AA-LHR on BA

Change would be:LHR-OSL//NRT-DEL//SIN-PER//MEL-AKL-SYD-SCL on LAN-MEX on LAN-GUA on MX-MEX ONMX-YYZ ONMX-LHRONBA

However mileage monkey claims MEX-GUA is invalid as Mexivana is not a One World carrier.

Wondering if my proposed changes are valid or not as I thought Mexicana was now a part of One World?
