At last, league tables in which UK airports are moving up. According to just-released data from the aviation schedule analyst OAG, Heathrow and Gatwick are improving relative to the global competition (compared to figures in 2019).
The metric being used? The number of seats departing on flights in August. A more valuable measure, you could contend, would be the actual number of passengers. But that data will not be available for many weeks, and this very busy summer there is a strong correlation between capacity and numbers carried. So available seats is a valid way to compare the world’s mega-hubs.
