This week's publication of OAG's annual Megahubs Index report again shows Heathrow as Europe's most connected airport by a considerable margin.
Using a calculated Connectivity Index based on seat capacity and number of destinations served, LHR comes in about one third higher than both FRA and AMS and more than 50% higher than CDG.
Of the world's airports, Heathrow ranks 15th for connectivity, with all but 2 of those higher in the list being in the US, plus Jakarta/CGK and Haneda.
