Indeed - I must have been looking in the wrong place, I see it now.
Good tip on parsing the URL, I see that there are many international dests available this way, and it satisfies the OP's quset to reduce clicks.
I see that you can also use the common "multi-airports, one metro area" designators, such as "LON" to get "London All Area" without having to enumerate each 3 letter airport code.
