Sustainability and environmental responsibility have been a growing focus at Pittsburgh International and Allegheny County airports in recent years, from a groundbreaking microgrid to a grassroots apiary program.

Many of our airline partners champion environmental initiatives, including Frontier Airlines. The 100th plane in the ultra-low cost carrier’s fleet honors Chinook, a female wolf-dog hybrid rescued in Colorado in 1993 that has become a symbol of conservation and awareness efforts for her species. Casper Wood caught a glimpse of this special aircraft at PIT.

And sometimes you can take “going green” literally, like our Customer Service Representative Laura Richardson did several years ago. On a Christmas trip across the pond, she captured a brilliant view of the Emerald Isle, and there’s no better time for a photo of Ireland than St. Patrick’s Day.

Thanks, Casper and Laura!
