Shannon-Heathrow passengers down 9pc
Passenger traffic between Shannon and London's Heathrow airport slumped almost 9pc last year as Ryanair expanded services to Stansted.
An analysis of figures by the Irish Independent shows that just under 232,000 passengers flew between Shannon and Heathrow last year, compared with almost 255,000 in 2013.
But the number of passengers flying between Shannon and Stansted jumped 10.4pc to 201,337 from 182,226.
The figures - compiled from data made available by the UK's Civil Aviation Authority - will increase pressure on stakeholders in the region to convince the Government of how important a Heathrow connection is to the region.
Passenger numbers between Shannon and Gatwick last year were 103,114, virtually unchanged from 2013.
Between Cork and Heathrow, passenger numbers edged 1.3pc higher last year to 397,867. Between Cork and Stansted, the number was up 40.8pc to 256,672. Ryanair boss Michael O'Leary has insisted that the Government needs to sell off Shannon and Cork airports, as well as the two terminals at Dublin Airport.
