A report by anna.aero received today prompted me to read up on 'Istanbul New Airport Megahub'. Phase one is planned to open in 2018, featuring three runways, a 90 million capacity terminal (plus a smaller one), 4 million square metres of apron space, and all the customary major airport fixtures and fittings. Impressively quick timescale for delivery too. The cost for this project is quoted as EUR10.2 Billion, which today converts to a grand total of £7.2 Billion.
Do you realise that you could build just over one third of a runway at Heathrow with that kind of money? Top value for UK plc!
You need to eliminate any fx issues and adjust for PPP to make a truer comparison.
