Money can't buy happiness, and as it turns out -- it can't really buy legroom either.
In a recent article from the Harvard Business Review, our favorite brainiacs conclude that on a plane, "there’s no correlation between price and comfort, including legroom." Total. Bummer.
After surveying roundtrip airfares, the authors noted that people paying less sometimes got more legroom than those paying more, with a difference of a few inches of seat pitch. "Seat pitch" is how airlines determine how much room you have in your seat -- and though it isn't an exact measure of legroom, it's a good indicator of the space you'll get.
Before your flight, ask the check-in desk (kindly, of course) if there are any exit row seats available on the plane, though your added inches will come with added responsibility. You can also always use TripAdvisor's SeatGuru to secure some awesome seat advice about what seats are best on certain airlines, or just bookmark this guide to airlines with the worst legroom so you know which planes to avoid (Hint: stay away from Spirit Airlines!). Otherwise, try flying JetBlue for their "Even More Space" seats that offer 38 inches of legroom in economy, or "core" as they call it.
And if all else fails, you can always book this $43,000 ticket for a Residence suite on Etihad Airlines. Since it's nowhere near economy seating -- and actually better than first class -- you'll DEFINITELY get enough legroom.
