Hi, I have a portion of an award flight - from JFK to ZRH, that me and my wife will fly next month. We do need to depart from AUS to JFK, so we plan on buying separate tickets for the AUS to JFK segments. After we do that, can I call the airline to combine both? It's convenient not having to take out our luggage and re-enter security. We do have pre-check which is good, but just want to avoid the luggage check etc if we can. Our other option is to use our SW RR points and have my wife fly on companion ticket, but SW does not fly to JFK, and we are trying to avoid having to ride a cab from either LGA or EWR.
