PDF tickets not going to Passbook.
Hi, so I have an iPhone 5 iOS 7.1 and I bought a few tickets for the movies which have been sent to me as a PDFs. When I click on the link to open in Passbook it just opens up the ticket in a tab in Safari. Then when I press the rectangle/arrow feature to copy/message/mail it etc it allows me to open with iBooks which is fine but isn't the purpose of Passbook for situations such as these? I mean the email specifically has a link to open in Passbook but why doesn't it?
Thanks in advance,
iPhone 5, iOS 7
