Ugh. This takes away the only real benefit, and replaces it with 'options' for benefits I already have. If I wasn't tied to AA (only airline to my outstation), this would be a signal to switch airline programs to Delta or United knowing that I can use Hyatt choices as backup options on AA. This isn't a benefit program for elites in both programs, it's now a benefit for non-AA elites to pick up a backup airline status on AA via their hyatt program.
Two thumbs down.
