Almost 700 more flights have been added by Jet2.com and Jet2holidays for summer 2022 in response to demand.
The move sees more capacity from Glasgow, Leeds Bradford and Newcastle airports just a week after the programme was introduced for next year.
A number of city break destinations have also been included as part of the capacity hike from the three bases.
Additional flights to 19 destinations will run from Glasgow, 15 from Leeds Bradford and 12 from Newcastle.
Destinations include the Canary and Balearic islands, Portugal and Turkey.
Amsterdam, Barcelona, Budapest, Paris, Rome, Krakow, Nice and Prague are among the new city breaks giving 49 destinations from Leeds Bradford, 35 from Newcastle and 29 from Glasgow.
Chief executive Steve Heapy said: “We know there is a lot of pent-up demand, and since putting our summer ‘22 programme on sale we have been very encouraged by the number of bookings coming through from customers and independent travel agents.
“Customers clearly want their all-important holidays to look forward to, so we have responded quickly by adding thousands of additional seats to a range of brilliant hotspots from these three bases.
“We haven’t stopped there though, and we are delighted to be adding a range of fantastic city break destinations for summer ‘22 too.
“The response to our summer ‘22 programme shows how much customers want to get away with an award-winning airline and tour operator to the sunshine, and we’ll have more good news to share soon with customers and independent travel agents across the UK.”
