After spending over a year in the US, and enjoying all of the mileage offers available to people here, I am bound to return to my homeland, France.

Since I have accumulated a certain amount of miles and status in a number of accounts while living here, I am now facing the question of what to do with all those accounts.

I would be interested to hear opinions of fellow Flyertalkers with similar experience.

I believe my future travel patterns to be mostly throughout Europe, with the occasional business/leisure trip to Asia and America.

Here are the accounts that I am considering keeping:
- AF (obvious reasons)
- AA (Status + OneWorld)
- NWA (KLM)
- Hilton (Status + International presence)
- Starwood (Status + International presence)
- Priority Club (International)

Here are the ones I'm thinking of getting rid of:
- UA (insignificant amount of miles)
- America West (insignificant amount of miles, no International)
- Southwest (points do not carry, no International)
- Marriott (insignificant number of points)
- Radisson/Goldpoints (not available outside US)

Should I keep these accounts, even though I'm probably not going to be using them as much in the future ? If not, do you have suggestions on what to do with these insignificant amount of miles.

Also, I would be interested to know what my options are, in order to be able to maximise earnings while living in Europe.

Can/should I keep my US address registered on those accounts, so that I do not get automatically shut out of promotional offers ?

Any help will be greatly appreciated.
