Ryanair has announced cuts in its summer schedule at Dublin Airport, saying it will result in the loss of 200 jobs among pilots, cabin crew and engineers.
The airline has blamed the Government's decision to bring in a €10 travel tax from April.
Ryanair will cut the number of planes based at Dublin from 22 to 18.
The airline earlier this month announced cuts in its Shannon services.
Elsewhere, as many as 600 jobs are at risk at Richard Branson's airline Virgin Atlantic.
The airline said it was 'currently consulting with staff about the possibility of up to 600 redundancies across the business'.
Virgin went on: 'We are keeping our staff fully informed and will be working closely with staff and union representatives in order to find ways to protect as many jobs as possible and avoid compulsory redundancies.'
Virgin Atlantic Chief Executive Steve Ridgway added: 'No airline is immune from the recession and we continue to reshape our business to ensure we're in the best position for the longer term.'
