Aer Lingus Regional, operated by Stobart Air, will allow Bristol-based passengers to fast track their journey to the US through Dublin from next spring.
From 1 May, passengers flying out of Bristol will be able to fly Aer Lingus to Washington via the Dublin transatlantic hub.
Completing pre-clearance at Dublin Airport means that on arrival in the US, Bristol passengers will be treated similarly to domestic passengers and avoid delays of up to two hours at security checks.
The Dublin-Washington route will operate four times weekly.
From summer 2015, Aer Lingus will also operate daily flights from Dublin to San Francisco and four weekly flights from Dublin to Orlando.
