Workers involved in ground handling at Palma de Mallorca airport are expected to strike over a four-day period during the summer holiday season, according to reports from UK outlets. The planned industrial action is expected to affect airport operations at Palma de Mallorca, with passengers warned to anticipate longer wait times. Sources say that queues may build at check-in facilities and at boarding gates as staffing levels change during the strike. The reports describe the action as being carried out by airport ground handling staff, rather than airline pilots or cabin crew. The outlets also highlight that the disruption could occur across multiple days, increasing the likelihood of delays or congestion for travelers arriving to catch flights during that window. Specific details such as exact dates and the size of the potential disruption are not provided in the supplied excerpts. Overall, the information indicates that holidaymakers using Palma airport during the strike period should plan for possible delays and allow extra time for airport procedures.
