Extract Cancel URL from Lufthansa pkpass
Couldn't actually verify if the URL worked but the cancel action showed up in the UI.
The URL seems to have a format of https://mobile.lufthansa.com/service/checkin?ENC=someverylongid&partnerId=00000001
. Unfortunately it's at the end of a sentence, so I have to do some more involved RegExp as to not count the period at the end of it.
