To avoid its cruise ships running into issues related to labor strikes that are scheduled to occur in Spain, Portugal and Greece, Royal Caribbean has altered itineraries for Independence of the Seas.

Independence of the Seas will skip a stop in Lisbon, Portugal on November 14 and will instead call upon Lanzarote, Spain.

Royal Caribbean spokesperson Cynthia Martinez commented on the changes, "We were aware of the upcoming strikes and proactively made changes to some itineraries."

The general strikes are expected to last three days and disrupt air travel as well as public transportation.
