Surprised not to have seen this posted yet…alas, T1 and T2 are connected by the “magic corridor” therefore meaning you can avoid the absolute zoo of T1 security and use T2 and also enjoy the superior shops/dining before wandering across to T1.

I used to commute DUB/BRS on a tri-weekly basis pre-pandemic, so got to know all of the little hacks. It’s worth keeping in mind that the Ryanair 100 gates at DUB are a bit of a walk over the “bridge of doom” and its worth factoring in 15 mins of walking time for any arrival plans.
