(CNN)For the second year running, seat-kickers have earned the dubious distinction of being America's most annoying airplane passengers.

The tap, tap, tapping with intermittent knees and feet to the back irks 61% of Americans surveyed for Expedia's third annual Airplane Etiquette Study.

Inattentive parents rank a close second, with 59% of respondents registering their aggravation with moms and dads who let their kids run wild.
