Air traffic control advised JetBlue flight JetBlue767 to look out for nearby northwest-bound traffic bearing the callsign "Echo-Three-Tango-Foxtrot" just before 6:15 a.m. UTC on Dec. 23, according to an X post by @aeroscouting in the reporting window from 4:45 a.m. to 6:15 a.m. UTC. The traffic advisory occurred over the past 90 minutes amid ongoing U.S. military aircraft movements in the Caribbean, including at least 13 F-35 fighter planes over Puerto Rico and military flights recorded in Trinidad and Tobago earlier on Dec. 23, as reported by journalist Nando Curbelo RodrÃguez and X user @eduardomenoni. U.S. Southern Command has confirmed heightened regional activity under Joint Task Force Southern Spear, with prior deployments of F-35As to Puerto Rico and other assets to support operations, per statements and satellite imagery from Dec. 22-23.
