Trying to help out a friend to pick a better FF program.
Here is her info:

1. She's currently a member of M&M (from LH).
2. She flies (with her family) from United States to Europe 1 to 2 times a year, always on discounted economy.
3. She rarely flies intra-United States.

Her issues/questions:

1. She complains she never has enough miles to either upgrade from Y to C on LH or use a free ticket (my assumption is that her miles are expiring for some reason).
2. She would like to pool her family's miles together to get a free ticket. I know M&M doesn't allow that, but is there a program that does? (Or is there a service to transfer miles between people for a cost)


What program(s) would you recommend she really join and credit her miles to?

If you have any other questions that would help decide, please let me know and I'll do my best to answer.

Thanks!
