The firm reported a 50% increase in post-Christmas sales compared to the same time last year, with around 43% of bookings for travel in the next 12 weeks.
Not Just Travel co-founder Steve Witt said pre-Christmas sales were down due to the uncertainty surrounding the Omicron variant, but as the booster jab rollout progressed, confidence returned.
Witt also claimed the traditional model of peak sales has changed and predicted there won’t be a "big extreme" peak in January.
"Demand will be high, but will remain high and not dip like it normally does," he said.
