So maybe this is obvious but I just want to confirm my understanding. If I am the miles collector in the family and am traveling with my spouse, one of us on a miles ticket and the other for $, is it always better to give the free ticket to the spouse? If I fly on my own ticket I get the EQM and status bonus whereas if it were the other way around I may get an upgrade but the miles would go to my wife.

Am I missing something or is this pretty trivial?
