Rachel Reeves’s bid to expand Heathrow could add £40 to airline ticket

Exclusive: Treasury analysis shows ticket prices expected to go up across board with no plans for frequent flyers to shoulder more of the cost

Rachel Reeves's bid to expand Heathrow airport could add 40 to the cost of an airline ticket, according to the Treasury's own analysis.

The chancellor's proposal to minimise the carbon emissions of a bigger Heathrow include the use of sustainable aviation fuels, which experts say are expensive and unlikely to reach the scale needed for aviation expansion.
