Ryanair says 1,000 new jobs will be created as a result of the government decision to scrap the travel tax.
The €3 charge for air passengers was dropped in the Budget yesterday.
Ryanair says traffic at Irish airports has fallen by seven million people since the travel tax was introduced in 2008.
The carrier says that much of this traffic can now be recovered thanks to the abolition of the travel tax, which it says makes Ireland a more competitive and attractive destination for visitors.
The airline says it will grow its passengers by at least 1 million in response to the move which will result in the jobs at Irish airports, as Michael O'Leary promised to do on The Right Hook here on Newstalk last week.
It has invited all the main Irish airports - Dublin, Cork, Shannon, Knock and Kerry - to meetings in Dublin on Thursday and Friday to finalise these plans and how it can be split between them.
Ryanair says it expects that this traffic growth will be focused on a range of new routes and additional frequencies on existing ones.
Michael Cawley is the Ryanair Deputy Chief Executive.
While Transport Minister Leo Varadkar says more detail of the Ryanair proposal is needed.
