Amid ongoing conflict, Ryanair said that it has to cancel 24 flights on July 20 as pilots prepare for their second of three one-day strikes on July 12, 20, and 24. The Irish Airline Pilots’ association said that it found some common ground with airline management during their July 11 negotiations regarding a proposal for a joint working group which could help both sides agree on a fair method to govern base transfer arrangement and related issues. However, the union called a strike when they failed to reach an agreement on the terms of reference for the proposed group.
