BERLIN — A four-hour ****** called by a pilots’ union in Germany at Ryanair has prompted delays, but the budget ******* didn’t have to cancel any flights.

The Cockpit union had called on Ryanair pilots in Germany to ****** from 5:01 a.m. to 8:59 a.m. local time Friday (0401 to 0759 GMT). It accused the ******* of staging a “publicity stunt” when it offered last week to negotiate on pay and working conditions.

Ryanair said nine out of 36 flights were ******* but there were no cancellations. It said in a statement that it was grateful to pilots for “largely ignoring” the ******.

Cockpit spokesman Markus Wahl told n-tv television the union was satisfied with pilots’ participation, asserting that Ryanair replaced contract pilots with non-permanent employees or foreign pilots.
