TIM Johnson is right in his assessment that the Heathrow third runway will not deliver on regional jobs and connections (Letters, June 20) and that the SNP should vote against it. However, he errs in suggesting that all Heathrow expansion is necessarily bad for Scotland.

The ludicrously high cost of the third runway will result in a likely doubling of passenger fees to £40, which will be added to ticket prices. This would make many connections to Scotland’s airports uneconomic for both passengers and airlines.

But our independent and alternative proposal to extend Heathrow’s northern runway would deliver the same economic benefits but it would be quicker, simpler and quieter.

It would also be at least £6 billion cheaper and would keep passenger fees flat, making regional routes far more viable than with the third runway.

Our scheme could also be constructed in phases, meaning that, if adding limited extra capacity threatens environmental targets, it can be paused or halted.

We urge the SNP to vote against the Heathrow third runway today and hope that our own commonsense solution will prevail.

THE public’s belief in the statements of politicians was somewhat shaken by the judgment on fracking in the Court of Session. The notification of the absence of Boris Johnson at today’s vote on the third runway at Heathrow gives that sore-tried belief another resounding jolt (“MPs to vote on third runway at Heathrow ... but without Johnson”, The Herald, June 22).

Here was the man who was so opposed to this project that he would “lie down in front of bulldozers”.

The Prime Minister, who has clearly been in agreement with the arrangements for Mr Johnson to spend some time abroad rather than voting against the third runway and having to resign his government position, must have had her tongue firmly stuck in her cheek when gilding the lily and describing her Foreign Secretary, the arch Brexiter, as “the living embodiment of global Britain”. Really?
