The Dublin Airport Fast Track pass offer is back again on the Vodafone app. Free fast track is useful especially in summer.
Edit: limited to 10 per person till 31st of August, they sent me 10 individual ones when you select 10. I've two spare if anyone needs them
Needs to be flying before 30th of September. I've sent the free ones I have
Seems to be working through that link even if your not a Vodafone customer
