Most flights between the U.S. and the Caribbean are already resuming or back to normal schedules as of January 4, 2026, with some minor adjustments and recovery flights still in progress today.

Whatā€™s happening right now

  • The temporary airspace restrictions over parts of the Caribbean have been lifted, which removed the main barrier to normal flight operations.
  • U.S. airlines began restarting flights just after the curbs expired around midnight Eastern time on January 4, and are spending the day rebuilding their schedules.

Airline-by-airline picture

  • Delta says it expects to operate its normal Caribbean schedule on January 4, with some timing tweaks while aircraft and crews reposition.
  • United has started by restoring flights to San Juan and is adding more departures through the day to clear the backlog of stranded passengers.
  • Spirit, Frontier, and other U.S. carriers report that flights to and from Caribbean destinations are resuming as the restrictions have expired.
  • American and JetBlue are also ramping back up and say they anticipate returning to normal operations in the region, while adding extra capacity (more seats, larger aircraft) to handle displaced travelers.

What ā€œresumeā€ means for travelers

  • Even though flights have technically resumed, you should still expect:
    • Some cancellations and delays today as airlines reposition planes and crews.
* Schedule changes (different times or aircraft) compared with your original booking.
  • Most major airlines have issued or extended travel waivers so passengers can rebook without change fees and, in some cases, fare differences for travel later in the month.

Practical tips if you have a trip

  • Check your booking frequently:
    • Use your airlineā€™s app or website (Delta, United, American, JetBlue, Spirit, Frontier, etc.) for live status and rebooking options.
  • Look for flexibility:
    • Take advantage of any fee waivers if your travel is flexible and you prefer to move to a later date once the rush of recovery flights eases.
  • Build in extra time:
    • Arrive early at the airport and plan for longer lines at checkā€‘in and security while airlines clear the backlog of passengers.

Forum-style ā€œQuick Scoopā€ take

People returning from New Year trips are seeing packed airports, recovery flights, and lots of ā€œschedule changedā€ notificationsā€”but not a long shutdown. Flights to the Caribbean didnā€™t disappear for weeks; they paused for roughly a day and are now snapping back, with airlines throwing in extra seats and larger jets to get everyone home.
