Ironically, in Moscow:
Moscow's airport rivalry highlights a paradox of the global aviation industry: Airlines compete fiercely with each other for customers, but they face many monopolist suppliers, such as air-traffic control systems, fuel distributors and airports. Resulting costs and poor services get passed on to travelers.
Regulators world-wide are starting to tackle the issue -- and some see Moscow as a paradigm.
Britain's competition authority, for example, last year considered breaking up BAA, the company that runs London's three big airports. In testimony before the regulator, officials from the International Air Transport Association, a trade group, cited Moscow as evidence of the benefits that competition could bring London's airport system. IATA testified that fees at Moscow's fast-growing, privately owned Domodedovo Airport are as much as 20% lower than at Sheremetyevo, the state-owned hub of flag carrier Aeroflot.
