Jet2.com and Jet2holidays are to start flying to Morocco with a 180,000-seat capacity programme from winter 2024-25.
Up to 17 flights a week will operate year-round to Agadir and Marrakech from six UK airports from October 2024.
The sister companies will operate to Marrakech from Birmingham, Glasgow, Manchester and Stansted.
Agadir will be served from Birmingham, Bristol, Glasgow, Leeds Bradford, Manchester and Stansted.
Three of the routes – Glasgow-Marrakech, Bristol-Agadir and Leeds Bradford-Agadir – are exclusive to Jet2.com and Jet2holidays.
More than 20 hotels are available in Agadir, a similar number in Marrakech, including Riad-style accommodation, and more 20 than hotels in the Marrakech area.
The expansion announcement comes almost six weeks after a 6.8 magnitude earthquake struck the north African country.
Jet2.com and Jet2holidays chief executive Steve Heapy said: “We are thrilled to be giving customers and independent travel agents even more choice thanks to the launch of Morocco as a brand-new destination.
“With year-round availability to the magical destinations of Marrakech and Agadir, we are giving holidaymakers access to two famous holiday hotspots.
“We are incredibly excited about these new destinations, and we know how immensely popular they will be with our customers.”
He added: “This latest expansion demonstrates the strength of our growing business, and it comes on the back of customers and independent travel agents choosing to travel with us time and time again.”
