Hello, I知 new here and making a big change, so I知 looking for some advice. Thanks in advance for any help.

Ive lived and travelled in Canada/US primarily until now. I currently have 250,000+ banked miles with Aeroplan.

Im moving to Houston and will be making round trip business class flights to Accra ~6 times/year. The best flights seem to be with KLM through Amsterdam.

I知 also planning to take a similar number of round trip flights from Amsterdam to Germany, but likely just for 1 year.

Long term I値l probably be spending my miles on flights within the US, or from Houston to Germany.

I don稚 know much about the various programs, but Im assuming I should ditch Air Canada and chose either KLM or Delta.

Most important thing for me would be maintaining my status for priority services and lounge access, and if possible, extending the priority/lounge benefits to my wife when traveling with me.

Secondarily would be allowing flights from Amsterdam to Germany to be bought with miles. Could I use my banked aeroplan miles for that, or should I convert those to something else?

Also, since I知 moving to the US, wondering which credit card I should get to support the best fit FFP.
