Aer Lingus Regional is launching a new service between Shannon and Bristol in April.
The airline said it is introducing the daily route, which begins on April 3, as a direct result of the Irish government's recent decision to abolish its air travel tax that month.
The service will depart Shannon at 1010 and land in Bristol at 1140, while the return flight will leave Bristol at 1205 and arrive in Shannon at 1335.
Aer Lingus Regional, which is operated by Aer Arann, is deploying an ATR42 aircraft on the route.
Simon Fagan, Aer Arann's chief commercial officer, said: "We expect to carry 25,000 passengers on the Bristol route in the first year of operation."
Shaun Browne, aviation director at Bristol Airport, added: "The Bristol-Shannon route has proved popular with passengers when operated in the past. Now, with economic conditions improving in both countries, we are confident the demand is there for it to be a success again, making business and leisure travel between South West England and South West Ireland more convenient."
In October, one week after the Irish government abolished air travel tax, Ryanair announced that is launching eight new routes from Shannon airport (see news, October 24).
