bags

I’m definitely a newbie when it comes to budget flights over in Europe, but a question I had was what to do with checked bags during a layover when changing carriers?

We will be flying from Dublin to LGW on Aer Lingus, each of us checking our backpack. We will have a 3 hour layover there and then continue on to Bergen, Norway on Norwegian.

In this instance, should we arrive at LGW, claim our bags, go through security again (first checking in with Norwegian and rechecking our bags on the flight to Norway) and wait for our flight, or will the airport handle cross-carrier flights?
