I am wondering if someone could help advise me which skyteam program I should join? In the space of 2 weeks I am doing:

3x AeroMexico Business (J) Flights
1x Alitalia Economy Flight
1x Business Delta Flight

I mainly fly Oneworld alliance airlines (I hadn't even heard of skyteam until this year!), and being based in the UK, there is no obvious choice for me as I would very rarely fly KLM or Air France. I make quite a few flights in the states, so continental or delta could be an option perhaps?

Is there a particular skyteam program that offers the best chance to get status/miles that I should join?

I have a dormant continental one pass account with 0 miles from years ago which is still open...

Thanks in advance for any input!
