When flying out of new-to-me airports, I find it helpful to have an idea of what to expect. For those who feel the same, here was my experience on a Friday morning flying from Dublin to the States.
TL;DR: On a not so busy Friday morning, it took me 36 minutes to get to my gate upon arriving at the airport.
* 7:40 * Boarded a 41 bus from Mountjoy, and arrived at Terminal Two bus stop at 8:21. * It cost 2.60€; oins or leap card are the only accepted forms of payment. * Note: you must wave to the bus to indicate you wish to board. * The Terminal 2 bus stop is shortly after you see Terminal 2 on your left; the walk is only about 2-3 minutes. * 8:25 * Entered Terminal 2. * There’s 3 floors, checkin is at floor 1, and security/gates are on floor 3. * I did not need to check bags, and had mobile boarding pass, so I headed straight to floor 3. * 8:35 * Through security. * It was a constantly moving line to get through security this morning. They only scan your boarding pass to enter. Liquids out, electronics can stay in your bag. Belts, jackets, and shoes above the ankles come off. * 8:52 * Through preclearance/customs (for flights to the USA, you go through preclearance here in Dublin. There are ample signs indicating the way to preclearance. Your boarding gate is located after that.) * They scan your boarding pass to enter the preclearance area. There was a short line today. To pass, they scan your boarding pass, look at your passport, and take a photo. * Note: There were machines here to do another scan of your luggage. That step wasn't needed today; unsure when they choose to necessitate that. Signs did indicate you're allowed to bring water through this secondary security screening. * 8:57 * At my gate. * It took me 36 minutes to get to my gate upon arriving at the airport. Overall a simple process, though lengthy due to the second security check. The airport was not busy this morning, so I would suggest allotting at least an hour to get to your gate as a cushion.
