I thought the pool thing was cool until I realized it doesn't reset others expiration. That was fine but then when I was about to redeem some miles because my mother's were expiring I noticed this in the terms:

H. Upon joining a pool, individuals understand that miles are redeemed on a first earned/first redeemed and is based on the entire pool’s transactions.

As this reads, if I redeem miles from my pool, my mothers miles that expire soon won't be burned. Instead, my miles that aren't expiring bc I fly frequently with them will because I earned them earlier than she did.

I just logged into her account and booked a 10K reward because she has like 16K expiring. For sure 10K of those were used up.

Now, I'm thinking I won't burn the "pool" miles because my non expiring ones are going to get burned instead.

Just a FYI for anyone in a pool.

I should have researched this more thoroughly so I could have burned her remaining miles on magazines. FYI on that, it says redemption takes up to several weeks, and your miles can expire before the magmiles place tries to redeem. In other words, your miles don't get instantly redeemed when you go the magazine route. That's according to the terms there.
