YMMV, but I just used one of my Promo tickets from Coke (which appears to be roughly equivalent to a Black ticket) to get a FREE ticket to tonight's Star Wars Double Feature in IMAX. I was expecting to have a surcharge, but when they scanned it, the ticket just printed out, without asking for any upcharge. Ticket guy wasn't sure if it would work, but after looking up restrictions, said both Yellow and Black tickets should be ok, and Black tickets should work with no surcharge, but there would be a surcharge with Yellow tickets. Also, I used the barcode from the 2 promo ticket for one cap code offer that I had on my infrequently used Coke account, so not sure if that played a factor.
Some things which may work (please post if you try and let us know the result):
- Fan Event
- Regular black ticket from Costco or other source
- Yellow ticket: how much surcharge?
What definitely won't work:
- Red, green, silver tickets (they're excluded from Disney movies)
