The questions seem different now. The US Airways link showed me that no questions are currently available. The DL link is showing questions, but they are different.
1 (about Memphis, The Musical in movie theaters). True (2 miles/2 showpoints)
And, well, that seems like the only one
The SPG link gives me no questions are currently available also. So, I only get access to one question, and it's for DL. Weird.
