FILE- In this Jan. 18, 2019, file photo passengers wait in line at a security checkpoint at Miami International Airport in Miami. While security screeners and air traffic controllers have been told to keep working, Federal Aviation Administration safety inspectors weren’t, until the agency began recalling some Jan. 12. About 2,200 of the more than 3,000 inspectors are now back on the job, overseeing work done by airlines, aircraft manufacturers and repair shops. The government says they’re doing critical work but forgoing such tasks as issuing new pilot certificates.(AP Photo/Lynne Sladky, File)
