Your guess is as good as mine, pafan. I’ve only been able to find singles on PPL’s site. I think the only hope for more or better tickets is if ‘nova returns some of their allotment. I called the PPL center a week or so ago, and the guy I spoke to knew nothing about if or when they’d get tickets back. You might want to call, to see if you have better luck.
I’ve seen no update about LU’s (small) allotment, but I’m gathering that they went quickly to the high-priority folks.
