Today much of the world is much more directly or 1 stop connected than it was when a handful of major airports were connected and everything else went through them
I was hoping Turkish would be the one to go double daily to maximize the non-stop possibilities since its Istanbul creates far more 1-stop options than Dubai or Hong Kong.
This also explains the decline in Madrid -- few were really flying with an ultimate origin / destination of Spain -- Iberia just was a convenient connector
Spanish economy is in the toilet still. That's the main problem.
