Almost nine million people are expected to flying out of the UK with easyJet this summer.
Around 5.5 million of them will travel over the school summer holidays.
Spain is the most popular country with Malaga and Palma the top routes, followed by Amsterdam, Alicante and Barcelona.
The busiest day of the year for travel is predicted to be September 6 with more than 130,000 passengers travelling to and from the UK with the budget carrier on that day alone on more than 800 flights.
The expected 15 million passengers travelling across easyJet’s European between July 15 and September 30 network will have the opportunity to donate unspent foreign currency to charity partner Unicef, through the Change for Good campaign.
Since the campaign launched last summer £1.2 million has been raised which is being used to help Unicef’s life-saving work immunising children.
Customer service director Peter Duffy said: “Since last summer our passengers have donated generously to this fantastic Unicef programme with the money they raised having enabled Unicef to protect nearly 1.5 million children against polio and a further 2.5 million children and mothers against deadly childhood diseases and maternal and newborn tetanus. With even more travelling this summer we hope to surpass last year’s effort.”
