Airbubba:
If they did the published miss, looks like they took the 180 degree track on the VOR-Z Rwy 10 rather than direct ONBED on the RNAV (GNSS) Rwy 10 approach, according to unverified data from a flight tracking website.
Perhaps they elected the VOR Z because of the 200-foot lower MDA. (Confusing, ain't it?)
WestJets is an RNP AR intensive carrier, and perhaps usually does other vertically-guided IAPs when they aren't approaching one of their RNP AR airports.
Perhaps, a first glance at the charts when the weather is "going south" in paradise would be to go for the VOR Z.
