The typical DUB/BUD/MAD/CGD fares (the current lot of cheap ex-EU fares) tend to run on a six month advance purchase, so it's currently working from 18-19th December 2022, so if you're looking to Vegas at Christmas best get onto it. The BUD one was to Hawaii (very expensive hotels), LAX, SFO, LAS, SAN, PDX last time I looked.
