Ferry operators DFDS and P&O Ferries apologized for the long waits at UK border controls on Saturday, August 3.
Travelers heading to the United Kingdom suffered delays of up to 6 hours as they queued at the French port of Calais.
P&O Ferries' extra ships were used for passengers who missed their voyage, as queues continued into the evening.
DFDS warned on social media that the queues could last for 6 hours for people traveling from Calais. The company said that due to high levels of traffic at the Port of Calais, there were waiting times of up to 6 hours to complete all controls. Traffic at the ports in Dunkirk (Dunkerque, France) and Dover (England UK) was "free-flowing through check-in and border controls" throughout the day.
P&O Ferries apologized on Twitter for the wait times at the port of Calais.
"Checked in vehicles have been unable to reach the loading lanes due to queues at border control. This is then causing vehicles to be backed up past the check in booths."
The company added they had put on an additional sailing that evening from Calais to help with the passengers that had been stuck at border control.
