Aer Lingus has sold its subsidiary Timas to the Cendant Corporation, a US-based firm.
The Timas sale includes Galileo Ireland and the network service business Minerva. Galileo Ireland employs 60 staff from its base in Dublin.
It is believed Cendant paid around €15 million for Aer Lingus' 75 per cent stake in the group.
The sale is part of Aer Lingus' disposal of non-core operations. The airline is also selling charter airline Futura.
Cendant, the owner of Galileo International, is now the sole owner of Timas.
