What a heap of junk!
This is just a series of web views wrapped in a lame so-called app! There’s a page on Aer Lingus’s web site (dated 2012) that says, "Aer Lingus plan to launch a passbook app in the near future.” Well, it’s now 2014 and there’s still no support for Passbook.
This app is a waste of everyone’s time. Ignore it
