yeah, I've wondered about that myself. was told if i went over my three allocated travel days (still, why not at least 4 to get us back home??) that i was subject to a huge fee from delta and disclipinary action from pinnacle, up to termination. i had a few transoceanic trip planned this year so looks like i'll have to buy a zed/s...for myself and entire family.

i wish whoever made our travel entitlements system would lose thier job over this..nwa never excluded us from their buddy pass system, parents flying and limiting us on our t/o travel.

my parents flew on a zed high on dl a month ago...i tried telling them it's cheaper on just about any other carrier OTHER THAN a delta connection carrier. US, AA are still zed medium for parents so looks like that'll be their next travel plans.
