Valuing landing slots at Heathrow

Continuing my occasional series, the FT reported that Lufthansa had been tricked into paying £800 million for the 49% of BMI that they didn't already own, however "The value in BMI lies with its coveted take-off and landing slots at Heathrow, about a seventh of the total. Earlier this year, BMI put a balance sheet value on these slots at £770m."

The Times reckoned that BMI owned 11% of Heathrow's landing slots, so let's call it one-eighth in round figures. There are 471,000 aircraft movements at Heathrow each year, so that's 235,500 'pairs' (one to land, one to take-off) and BMI 'own' the right to land/take-off 30,000 times a year. £770 million ÷ 30,000 = £26,000 for the right to land/take-off once a year, in perpetuity.

Assuming that this right could be reasonably amortised over ten years, that's a notional cost of £2,600 per pair if you own them, and a real cost of £2,600 per pair if you have to buy them (cost of finance + uncertainty premium). In other words, if the local councils around Heathrow were allowed to auction off land slots, airlines would and could pay an average of £2,600 and still be profitable. Times that back up by 235,000 pairs gives local councils potential income of £611,000 million.

And the value of those landing slots is depressed by Air Passenger Duty. If we scrapped that crude tax as well, the annual 'rental' value of the slots would go up by another £673 million (67.3 million passengers at an average of £10 APD), bringing the total local revenues to a nice round £1.3 billion (rather less than my earlier estimate, I admit).

And in difficult times like these, the auction price would drop of course - in extremis to £nil in the short term. Great, that means that airlines can drop ticket prices by several per cent, which will hopefully keep things ticking over, minimise job losses and ensure that they recover much more quickly again in future (so the auction receipts quickly revive again, and so on and so forth).
