Hi all, Thanks for any help in advance.

1. What is most important to you in a frequent flyer program (FFP)?
Reply: Award bookings for international travel.

2. How many miles do you usually fly each year? How many flights/sectors?
Reply: 10k-20k, average maybe 12-16 segments.

3. What fare class do you usually buy?
Reply: economy

4. Are you able to choose your airlines and/or class of service? Do you travel for work and/or pleasure?
Reply: Lowest fare. 25%/75% personal/business.

5. Which routes do you fly most often?
Reply: Just depends on where a conference or trade show is, but 90% domestic out of Roanoke, VA

6. What is your home airport?
Reply: ROA. CLT and GSO are in reasonable driving distance, but not preferred.

7. Do you have status in any FFP? What is it? How miles do you have banked in a FFP, if any?
No status.
Miles/points:
DL - 2k
HA - 3k
UA - 8k
US - 5k

SPG - 42k
Chase UR - 80k

8. What are your preferred airlines, if any?
Reply: I suppose UA since my wife has a majority of her miles there (~60k), but I'm indifferent really.

I travel infrequently enough that I'll never earn status on an airline and luckily that's unimportant to me. What I'd like to know is, is there any one program I can use to aggregate miles from such variable travel?

I recently looked into AS since it appears that I can attribute both DL and AA miles to the same program (maybe US later?) and also transfer SPG points there as well. Is this a reasonable strategy? I doubt I'll ever travel AA or DL enough to book awards based on miles flown alone. But if that trickle of miles could be consolidated somewhere, it may make a difference. I also occasionally rent a car (2x a year) so if those rewards could go to a FFP, that may help.

My question for you fine folks is, what is my best strategy for aggregation?
