UPDATE: The strike has now been called off
Lufthansa pilots will walk-out for the fourth time in three weeks on Tuesday.
The industrial action is scheduled to take place at Frankfurt Airport between 0900 and 1700 local time.
It will affect all Lufthansa long-haul services — on A380, A330, A340 and B747 aircraft — at the airport, its main hub.
The strike has been called by the Vereinigung Cockpit union, which is protesting plans to change the current scheme that sees pilots retire at 55 and retain some of their pay until they reach the state pension age.
Pilots went on strike at Munich Airport last week (see news, September 9), at Frankfurt Airport the week before (see news, September 5), while a walkout in late August saw 70 per cent of flights operated by Lufthansa's budget carrier Germanwings cancelled (see news, August 28).
In April, a three-day pilots' strike saw Lufthansa cancel 3,800 flights (see news, April 1).
