The British-based low cost airline Easyjet has played down speculation that it has plans to locate services out of Dublin or Shannon.
A spokeswoman for the airline told RTE today it had talks with a variety of airport operators from time to time, but was having no active discussions with Aer Rianta at the moment.
The company is currently focusing on investing on its services out of Belfast - it recently increased its daily number of flights from there from 11 to 19.
Because of this, the company has ruled out further expansion into Ireland in the short to medium term.
Aer Rianta confirmed that it had had talks with both Go and Easyjet and had put proposals to both airlines about the incentives available if they were to locate here.
Aer Rianta is currently offering a full discount on landing charges for three years on new routes out of Shannon, and 75% discount in the first year on new routes out of Dublin.
A spokesman said it would actively encourage bringing new services into Shannon in particular to grow the market from there to new destinations in Europe like Scandinavia and Germany.
Ryanair, which returned services to Shannon last year, said it flew 275,000 passengers on its routes to London and Frankfurt in its first year. The company says this proves that there is considerable potential for growth in the low cost market.
