The Southwest Airlines Pilots Association has announced to members that they are considering pickets to have their demands met. Southwest Airlines pilots and flight attendants are experiencing increased work schedules with little notice, fatigue from understaffing, and a lack of food and hotels, among other things. Southwest has started offering referral bonuses worth $300 to staff to try and overcome their severe understaffing. Southwest says they are aware of the concerns, and they are working to address the issues.
