Caribbean airspace that was recently closed has already reopened , with restrictions lifted just after midnight on January 4, 2026 (around 12:00 a.m. ET / 05:00 UTC), but normal flight operations will take a few days to stabilize.

What has reopened and when

  • U.S. authorities allowed the temporary restrictions over large parts of Caribbean airspace to expire at 12:00 a.m. Eastern Time on January 4, 2026, meaning flights are officially permitted again from that time.
  • Notices to air missions (NOTAMs) tied to the closure are now in an “expired” or relaxed state, with only advisory-type language remaining in place for operators.

What travelers should expect now

  • Airlines are resuming schedules, but many carriers have issued travel waivers through January 6, 2026, which signals they still anticipate disruptions and rebooking needs over those dates.
  • Industry experts and airline forums report that cascading delays, aircraft/crew misplacement, and backlogs from cancellations will likely continue for several days even though the airspace is technically open.

Impact by airline and dates

  • Major U.S. airlines (including United and Delta) list January 3–6, 2026 as the key “impacted travel dates” for affected Caribbean destinations, and allow fee-free changes or rescheduling within that window.
  • After January 6, schedules are expected to look closer to normal, but some individual flights may still be adjusted as airlines reposition aircraft and crews.

Practical tips if you’re flying

  • Check your specific flight status frequently (app/website), because conditions now vary by route, airline, and airport even though the regional airspace is open again.
  • If you’re traveling January 3–6, review your airline’s waiver policy—many allow you to move your trip at no extra charge or cancel for credit due to the Caribbean airspace closure.
