... I mean, no. It's more that it is weird that there is no train to the airport (it looks like you can take ~3 trains from Manhattan). New York is likely the only really big city in the developed world where this is the case.

In Ireland, everyone thinks it's pretty ridiculous that there's no train to Dublin Airport (all going well, it will finally have one in 2036 or so, after _many_ false starts). Dublin's a city of about 1.5 million people. It's pretty incomprehensible that a city ten times the size wouldn't have one.
