Cabin crew trade union UFO has rejected an offer to mediate a dispute over pay and conditions with Lufthansa's Eurowings, raising the probability of strike action.
"It is more obvious than ever that the union does not want to find a solution," Eurowings human resources director Joerg Beissel said in a statement.
Eurowings put forward a new offer last week that includes an average pay increase of around 7%. At Germanwings, UFO said it has failed to reach an agreement on part-time contracts.
