Beckles, nice report...
A couple things: DL did away with the orange Priority tags earlier this year. The only tags available now are the white laminated PRIORITY ones used for Intl. flights.
If you & Pixie were on the same record traveling together, she should have had the same status as you for upgrades. When Jackie & I went to the PIP, my Gold got her upgrades that she wouldn't have gotten with her Silver. I confirmed that when I booked the tickets.
Anyway, welcome back & Happy New Year!
