72 Hour ESTA Requirements
Customers flying to the United States are reminded to apply for an ESTA no later than 72 hours before travel.
Changes to ESTA policy at the U.S. Department of Homeland Security mean that real-time applications will no longer be available. Passengers arriving at the airport without an ESTA may not be able to travel.
Customers can apply for an ESTA or check their existing ESTA status online at https://esta.cbp.dhs.gov/esta/.
