More than 80% of the firms’ trips are guaranteed to go ahead and more holidays will be added each week and viewable on the Travelsphere and Just You websites.
Alastair Campbell, G Touring’s managing director, said it’s "more critical than ever" the companies "do everything we can" to rebuild customer confidence and encourage bookings.
"Customers are now seeking surety that their long-awaited holiday will actually happen," he added. "Our amazingly supportive agents have also been staggeringly understanding of the necessity to amend and reschedule holidays due primarily to aviation and supplier amendments."
Travelsphere customers can choose from more than 60 holidays with more than 120 departure dates for 2022, with Just You offering Guaranteed Departures on 86% of 2022 trips.
