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.
