What You'll Learn

It's a 5-15 minute walk between T1 and T2
Yes, it is possible to walk between Terminal 1 and Terminal 2 at Dublin Airport. The walk between the two terminals takes around 5 to 15 minutes.
To walk from Terminal 2 to Terminal 1, you can go through duty-free and the restaurant area, following the signs for Terminal 1. You will end up just past Terminal 1 security. This is a fairly common occurrence for those flying with Aer Lingus, as they may have to check in via Terminal 2 but then depart from a Terminal 1 stand.
If you are flying with a different airline, such as Ryanair, you may need to go through security again at Terminal 1. This can add some time to your journey between the terminals. There may be queues at security, especially if there are multiple flights departing around the same time.
It is recommended that you have a pair of comfortable shoes, as you may need to walk quickly to reach your gate on time. Some airlines, such as Ryanair, may close the gate up to 5 minutes before departure to ensure they do not miss their slot.
Overall, while it is possible to walk between Terminal 1 and Terminal 2 at Dublin Airport in around 5 to 15 minutes, the total time may vary depending on security lines and the location of your gate.

You may need to go through security again
Yes, you can go from T1 to T2 at Dublin Airport. The two terminals are about a 5-15 minute walk apart. However, if you are transferring from T1 to T2 or vice versa, you may need to go through security again.
If you are flying with different airlines, you will likely need to go through security again. For example, if you are flying from Kerry to Dublin with Ryanair and then getting on an Aer Lingus flight, you will need to go through security again. This is because you will be leaving airside, going through customs, and then coming back in through security in T1 or T2.
Even if you are flying with the same airline, you may still need to go through security again, depending on your destination. For example, if you are flying to the United States, you will have to go through US preclearance in T2.
Additionally, if you have separate bookings for your connecting flights, you are considered a self-connecting passenger. In this case, you may need to exit and re-check in with your airline, which could involve going through security again.
It is important to allow sufficient time between your flights in case you need to go through security again and to account for any potential delays or queues.

Follow the 'Flight Connections' signs
If you are travelling outside of 06:00–13:00 hrs through Terminal 1, you must exit through Baggage Reclaim and go through security. However, if you are travelling within this time frame or through Terminal 2, you can simply follow the "Flight Connections" signs in both terminals.
If you are travelling from Terminal 2 to Terminal 1, you can follow the signs for Terminal 1. Go straight through the duty-free area, straight through the restaurant area, and you will end up just past T1 security. You can also follow the signs for the 300 gates, which will bring you to the other side of T1 security.
If you are travelling from Terminal 1 to Terminal 2, you can go through duty-free and head to the right. You will see signs at the far end for gates 100-335. Follow these signs, and you will find your way to the airside of T1 security.
It is important to note that you may need to go through security again, depending on your airline and destination. If you are flying with a different airline, you will need to go through security again so they know you are there. If you are travelling to a destination that requires additional security checks, such as the United States, you will need to go through the necessary clearance procedures in Terminal 2.
The walk between terminals is approximately a five- to fifteen-minute walk, so it is recommended to plan accordingly and allow enough time for any potential queues or delays.
