Bark Air, a new airline for dogs, will take its first flight Thursday

Bark Air, a new airline that puts dogs before their human companions, will take its first flight Thursday. 

Bark, a pet company founded in 2011 that sells dog food and other products, announced the new aviation experience for canines in April. It's the second air travel service to market itself as catering to pets before human passengers, recognizing how stressful and uncomfortable commercial air travel can be for animals. United Kingdom-based public charter operator K9 jets also lets passengers' pets travel next to them in the aircraft cabin, versus in crates in commercial aircraft cargo holds.

"We are excited to take the insights we've learned over the years to create an experience that is truly dog-first, which is drastically different from just accepting dogs – from the ground to the skies," Bark co-founder and CEO Matt Meeker said in April. "We believe this initiative will elevate awareness of our brand's mission and values, introduce more dog lovers to the Bark family, and help enrich the lives of dogs and their people around the world."
