Caribbean airspace subject to the recent closure has already reopened , with restrictions expiring just after midnight on January 4, 2026, and flights now allowed to resume, though disruptions and schedule changes may continue for several days.

What actually ā€œopenedā€ and when?

  • The U.S. restrictions affecting a large portion of Caribbean airspace were lifted shortly after 12:00 a.m. ET on January 4, 2026.
  • Notices to air missions (NOTAMs) tied to these restrictions are now in an advisory phase, meaning flights can operate but operators must still review risk and routing guidance.

What this means for your flight

  • Airlines and private operators are resuming services, but many flights over January 3ā€“6 were cancelled or rerouted, and knockā€‘on delays are expected for several days as schedules normalize.
  • Travel waivers from major carriers (like Delta and United) cover trips in the January 3ā€“6 window and typically allow free rebooking for affected passengers through around January 9, 2026.

Why there was a closure

  • The closure came after U.S. military operations and strikes involving Venezuela, prompting a temporary prohibition for U.S.-registered aircraft over parts of the Caribbean region.
  • The goal was to manage flight safety risks near active military activity; once the immediate risk window passed, the prohibition lapsed and was replaced with cautionary advisories.

Practical tips if youā€™re traveling

  • Check your airlineā€™s app or website for realā€‘time status; many are still adjusting schedules and reaccommodating passengers whose flights were cancelled during the closure window.
  • If your original travel dates were January 3ā€“6, look for a ā€œCaribbean airspace closureā€ or ā€œtravel waiverā€ bulletin, which may let you change dates or routes without change fees, as long as new travel starts by the stated waiver deadline (often January 9, 2026).
