Delta Airlines: also not perfect

So I criticized United a while back for a bit of dumb design in their online reservations system. It's only fair that I also mock Delta.


This is pretty straightforward. I'm trying to fly out of MacArthur Airport on Long Island, code ISP. Note that Delta's system is saying that there is no exact match for "ISP", but its best guess is in fact "ISP". Selecting this doesn't work, it just takes me back to this same page. I think the real problem is that there are no flights out of ISP to my destination, but this is quite simply broken behavior.

Disappointing.
