Heathrow Airport's slot machine: hitting the jackpot again?

British Airways now holds more than 50% of the slots at capacity-constrained Heathrow, thanks to its bmi acquisition. Nevertheless, BA had managed to grow its holding for years, mainly due to secondary slot trading. After years of uncertainty over its legality in EU law, the EU clarified its position in 2008 and allowed the practice. It went on to commission a 2011 study which concluded that slot trading had clear beneficial impacts at Heathrow.

In this report, CAPA analyses the small proportion of the total number of Heathrow slot trades where slot values have been reported in the media and elsewhere. For many years until the mid 2000s, the average traded value per daily slot pair calculated from such transactions was around GBP4 million. A series of trades at more than GBP20 million per pair captured headlines in 2007 and 2008 before the market went underground. Surprisingly, after such a long quiet period, 2013 has seen two deals valuing Heathrow slots at GBP15 million per daily pair.
