London's Heathrow has emerged the most connected airport, and Toronto's Pearson placed fifth, in a list that ranks the busiest megahubs around the world.

Compiled by air travel intelligence company OAG, the international megahubs index ranks airports by calculating the total number of possible connections between inbound and outbound international flights within a six-hour window.

For the report, analysts looked at the busiest day of the year for global aviation among the world's largest airports.

On a single day in July, there were more than 72,000 possible international connections between flights arriving and departing London Heathrow within a six-hour window.

After London, Frankfurt Airport and Amsterdam Airport round out the top three spots, proving that European hubs are the most international.

Overall, 16 airports from Asia-Pacific make up the top 50 list, while the U.S. has a dozen hubs.

The highest ranked North American airport is Chicago O'Hare Airport (No. 4) followed by Toronto Pearson International Airport (No. 5).

The most connected airport for Asia is Singapore's Changi Airport (No. 6).

Here are the top 10 international megahubs, according to OAG:

1. London Heathrow Airport

2. Frankfurt Airport

3. Amsterdam Airport Schiphol

4. Chicago O'Hare International Airport

5. Toronto Pearson International Airport

6. Singapore Changi Airport

7. Soekarno-Hatta International Airport, Jakarta
