For example EWR-TPE one way with the EWR-HKG segment on UA and HKG-TPE on CX.
Is it safe to use your FF info for the UA segment on something like this?
Generally speaking, airlines pretty much never check whether you fly the entire itinerary, carrier change or no carrier change. If you no-show for a segment then you're offloaded from that flight, the rest if your itinerary (if any) is of course cancelled and no one will look at that ticket/record ever again.
You're looking at booking EWR-HKG-TPE on UA/CX and just getting off in HKG? For a once or twice occurance then no issues whatsoever using your UA number. Not sure what this has to do with AA though.
