I'm scheduled to fly into Lisbon May 17. According to the article that is not one of the strike days. However, I'm scheduled to fly out of Lisbon on June 11, which is one of the strike days. I'm not sure how to keep informed on this. If anyone on this feed gets updates, I would appreciate knowing. Thanks for posting this! (Hopefully, the unions and government can come to agreement before these strikes actually take place.)
