German airline Lufthansa has cancelled dozens of flights to and from the UK and Ireland tomorrow due to strike action.

Around 100 flights have been cancelled at airports in London, Manchester, Birmingham, Newcastle, Glasgow, Aberdeen, Edinburgh and Dublin.

The German airports affected by the strike are Frankfurt, Munich, Dusseldorf and Hamburg.

The one-day strike, which is due to a pay dispute, will result in only about 20 of more than 1650 scheduled short-haul flights operating.

The airline said many long-haul services will also be hit, with only six of 50 planned flights operating from its main Frankfurt hub, and only three of 17 in Munich.

Passengers affected by the cancellations can re-book for free, Lufthansa said.

The ver.di trade union announced the one-day "warning strike" – a tactic commonly used by German unions to raise pressure in wage talks –on Friday.

Last Wednesday, Lufthansa rejected the union's demand for a pay increase of 5.2% over the next year as well as job guarantees.

Last year, the airline and a union representing cabin crews called in an arbitrator to settle a pay dispute after the union staged a series of short-term stoppages that caused numerous flight cancellations.

Last month the airline's Lufthansa Regional service launched its maiden flight from Glasgow to Düsseldorf.

The inaugural flight was the first to link the cities in two decades.

On the flight were delegates from the Scottish Chambers of Commerce and Scottish Development International, aiming to attract successful businesses from Germany's prosperous Rhine-Ruhr region.

German visitors currently pump more than £19 million into the Glasgow economy every year.

Lufthansa Regional will operate six flights a week until June when there will be flights to Düsseldorf each day.

At the time Stuart Patrick, of Glasgow Chamber of Commerce, said: "Germany is an important market for Glasgow."

And Gordon Matheson, city council leader and chairman of Glasgow City Marketing Bureau praised the new route.He said: "There will undoubtedly be strong demand for this service from the business community."
