12 busiest domestic passenger air routes in the world

Guess the world cities sharing the 12 busiest domestic passenger air routes. Some cities appear more than once :)
Countries are listed alphabetically and appear once you type in a city correctly.
In true Jetpunk style, the Taiwan/China route is not considered domestic, but you can still guess the cities.

Hong Kong to Taipei is an international flight. Naha should be accepted for Okinawa. Jeju doesn't have an L at the end. Otherwise great quiz.

Thanks for your comment. I've already pointed out the Taiwan exception in the caveats, so it's staying in the quiz; that's why the countries are automagically given for this route. I've added Naha as an acceptable type-in (waiting for re-approval) and fixed the typo. Cheers.

Just FYI, Naha doesn't seem to work.

I did -- but I only corrected the type-in. I've corrected how the answer appears as well now thanks.
