No. 2: Kennedy International Airport

At Kennedy, two of the terminals, occupied by American ( AMR) and JetBlue ( JBLU), made our most beautiful list.

But the terminal occupied by Delta ( DAL), considered to be gorgeous when it was occupied decades ago by Pan American World Airways, makes the ugly list. JFK received 17.5% of the votes in our poll.

The disdain for its terminal is not news to Delta, which plans a $1.3 billion renovation. As one reader commented, "the Delta terminal at JFK is an embarrassment for the largest carrier." Another said Delta's JFK terminal is "hands down" the ugliest. "They are hamstrung by an incredibly inefficient operation from the passenger point of view, and the terminals, alleys and passenger spaces are largely to blame. T4 can't come soon enough!"
