I'm travelling from Newcastle to USA and transferring at Dublin.
The entire trip is with Aer Lingus. They quote a time gap between landing and take-off at Dublin of 01h10m. They assure me the timings are OK.
Are they right or should I worry?
Dublin Airport isn't that busy at all. Apparently there is a separate line for Transfers. As you are not changing the airliner I don't see any problem. If you are holding EU Passport then the queue will clear off very quickly.
if it is with the same company and you don’t have to re check you baggage then I don’t see any problems, but you have to be aware that they might be delays do weather or others conditions, if you have to re check your baggage I find it pretty difficult so I would advise you against unless the airline takes responsibility for you to be on time or else send you free of charge in a another
