Once again, we're number one! In bad airports. Hot on the heels of a similar report, for the fourth year running LaGuardia has been deemed the worst airport in the country according to a Zagat Survey of 8,007 flyers. Not that JFK and Newark did much better, coming in 26th and 24th out of 30, respectively. Meanwhile, Portland International got the nod as the best airport in the country. So is there anything that could fix poor beleaguered LaGuardia? "Knock it down and start over," suggests Zagat's founder Tim Zagat. But hey, with a slew of fancy food spots coming to LaGuardia's Terminal D soon enough, at least folks can eat good food while they wait.
