Layovers can take your vacation from a relaxing “ahhhh” to a frustrated “argh” pretty quickly. Even if it’s just a short one, you still have the hassle of deboarding your original plane, running to your next gate, standing in line, boarding and getting all settled in again. If you’re looking for inspiration for your next vacation and you’re open-minded about where to travel, consider cities you can fly to directly from Denver.
