By the same token, travel executives who are striving to be greener might find it interesting to hear about how Bombardier now manufactures its private jets with an Environmental Product Declaration, meaning sustainable sourcing, right down to the wood veneers in its jets that can fly 17 hours nonstop.

Even though I don’t sleep well on airplanes, I can always dream.
