Children under 12 will be able to fly free from Heathrow to Newcastle and Leeds Bradford on British Airways flights during the Rugby World Cup.
The deal is available until November 1 to cover the duration of the event, making it easier for families to get to matches at St James’ Park, Elland Road and Twickenham.
The ‘Kids Fly Free’ initiative follows the cut in Air Passenger Duty for under-12s from May and an extension of the tax cut to under-16s from May 2016
Dale Keller, chairman of the A Fair Tax on Flying campaign, said: “This initiative is a great example of the benefit a cut in Air Passenger Duty for children has brought to families across the country.
“The UK still has the highest air travel tax in the world and it is a barrier to boosting our tourism industry and a burden on hardworking families taking a well-deserved holiday.
“The government should follow BA and Heathrow’s lead and put consumers first by further cutting this damaging tax.”
Andrew Bridgen, MP for Northwest Leicestershire who led the campaign to scrap the tax on family flights, added: “The campaign to scrap Air Passenger Duty on children’s flights was a huge success and this announcement is great news – it shows the benefit scrapping this tax is having for hardworking families.
“APD is a significant barrier to travel and tourism in the UK and the evidence is clear: cutting APD stimulates economic activity and brings benefits to the entire country.
“The Chancellor needs to listen to the evidence and do more to further reducing this damaging tax.”
