Tui UK has added more than 100,000 extra holidays on sale for next summer to cater for increased demand.
The operator is offering an additional 1,500 hotels in 62 destinations.
It said families in particular want to book ahead, with May the most popular month for travel.
The most popular destinations for next summer are Greece, Cyprus, Turkey and Florida.
Long-haul has increased in popularity with all customer groups, and families in particular want to plan far ahead, said the operator.
Almost a quarter (24%) of Tui customers have chosen to go away for a longer break compared to 2019, “indicating their desire to make up for lost time and treat themselves”.
Last week, Tui Group said it will reduced its capacity for summer 2021 from 80% to 75% of 2019’s level, with summer bookings appearing to have stalled.
It reported strong UK bookings for 2022, noting: “We continue to see strong pent-up demand in the UK, with bookings for summer 2022 now around 120% higher compared to summer 2021 bookings.
“Bookings for May 2022 are recording an increase of more than 150% compared to May 2021.”
Elsewhere, online travel agency Thomas Cook said it is “seeing a shift from people booking this summer to looking much further ahead”.
A spokesman said: “There remains a lot of interest for this summer but people are more confident booking for 2022.”
He noted consumers are booking more longer stays and “splashing out a bit more”.
