Spain is to allow all unvaccinated British children to enter from 14 February.
Children aged 12 to 17 who aren’t double-jabbed will be able to travel with a negative PCR test taken up to 72 hours before arrival.
Younger children are already able to travel to Spain without the vaccine.
Jet2 CEO Steve Heapy said: “This is very welcome news for families who want nothing more than to holiday in their favourite Spanish destinations.
“We are pleased to see the Spanish Government taking positive action to welcome more arrivals from the UK and we know that this will lead to an increase in bookings.
“As the UK’s leading tour operator to the Canary Islands and Balearic Islands, with a huge programme also on sale to Mainland Spain, we are already seeing strong demand and this will boost that even further.
“The removal of the requirement for 12-17 year olds to be double-vaccinated tells families that travelling to Spain is returning to normal, and after two years of missing out we know how much everyone wants to experience that famous Spanish sunshine again.”
