SIPTU is holding a public meeting in Shannon this evening to highlight its concerns over proposals to privatise Aer Lingus.

The meeting will also address the union's opposition to changes in the current bilateral air agreement between Ireland and the US, which will see a reduction in the number of transatlantic flights coming into Shannon after 2008.

SIPTU organiser in Shannon, Tony Carroll, said the meeting is part of a rolling political campaign intended to express members' fears.

TDs and Senators from the region have been invited to attend to address these issues.
