Oneworld

Hi folks

TL;DR American *A silver member, going to live abroad for a few years, planning to book multiple full price business fares from RJ and looks to maximize his rewards. Need help to decide which program to use.

I’m currently a soon to become star alliance silver member (their first tier from basically just joined).

I’m considering to move overseas for a while and I’ve found royal Jordanian to be a good fit for my needs since I can comfortably pay cash for round trip business class tickets using that airline without too long of a layover.

I’m a situation like this, it really makes sense to start a oneworld account. I’m from US and will temporarily live in Eastern Europe for a few years to come and will head back to US afterwards.

In my situation, I was thinking to choose a loyalty program to earn my status. I currently have a membership with Qatar but all of my miles have been expired.

So the question becomes as follows:

Which airlines’ loyalty program should I go with? Should I use my US address for the loyalty program or my non-US address?

My main uses for loyalty points would be business upgrades for long haul flights and priority check in lines and lounge access. For award booking I may transfer miles using my credit card (I’m currently with CSR and may join C1 VX in future).
