Add comments from the budget airline MADRID, July 29 (Reuters) - Spain-based pilots at easyJet EZJ.L will go on strike for nine days in August to demand better working conditions, the SEPLA union said on Friday. Airlines face labour disputes this summer as a steep rebound in tourism has led to staff shortages while soaring inflation encourages cabin crews and pilots to demand higher wages and better conditions. On Thursday, Spain-based cabin crew at easyJet suspended a planned strike scheduled this weekend after reaching a deal with the airline that includes higher salaries, the USO union said.
