In the first 10 days of the month, the Transportation Security Administration screened an average of 804,302 people a day, down nearly 66% from the same period a year ago.On Friday, Southwest proposed the 10% pay rate cut to its roughly 9,000 pilots. The union, the Southwest Airlines Pilots Association took issue with the across-the-board reduction and force majeure clauses, which it feared the airline could lean on to furlough pilots anyway.”This addition would not protect us from furloughs or ensure us that our hourly trip rates would snap back after the term of any agreement,” the union said in a memo to members.The union pointed to other options like voluntary time off at reduced pay and early retirement packages.”We have a revenue and short-term cash problem that cannot be fixed by concessions alone,” the union said in a memo on Friday. Its president Jon Weaks, told CNBC the company’s proposal is “dead on arrival” but that the union is open to further talks on cost-cutting measures.The dispute comes as competitors American Airlines and United Airlines earlier this month began cutting more than 30,000 jobs after the terms of billions in federal aid expired. Southwest doesn’t plan to furlough workers this year but earlier this month said it would seek concessions from unions for a committment to keep jobs through 2021.United Airlines pilots agreed to reduce minimum hours in order to prevent close to 3,000 furloughs planned this year.
