IRISH travellers are facing further uncertainty after a strike at Berlin's two main airports was extended further.
Today's industrial action by ground staff at the Tegel and Schoenefeld airports led to major delays for passengers.
Staff began their strike action at 4am and were due to finish at 5am, however it was last night further extended by another 24 hours until early Wednesday.
Several flights into and out of Ireland were cancelled including Ryanair flights from Belfast and Dublin and Aer Lingus flights from Dublin, causing further misery for passengers already hit by industrial action last week.
Travellers hoping to return to Ireland were also forced to extend their stay in Germany after return flights were also affected.
A spokesman for Berlin airports said almost all flights would be cancelled on Monday - 194 at Schoenefeld and 448 in Tegel.
Ground crews have already walked out several times over the past few weeks amid a tense dispute over pay. On Friday, a similar strike led to nearly 700 flights being grounded at the two airports.
The service workers' union Verdi is demanding higher wages for around 2,000 workers handling passengers and baggage.
The union wants a pay rise for ground staff to €12 per hour from around €11 euros with lowers offers from management already dismissed by the unions as unacceptable.
Ground staff jobs include checking in passengers, loading and unloading baggage and cargo and directing aircraft on the tarmac.
