Sin City
Las Vegas sits in a desert valley ringed by mountains, with the Strip's resort corridor forming a single dense spine surrounded by a much larger, ordinary, car-built city. Most visitors never see far beyond that corridor and the older casino blocks of downtown a few miles north. A short monorail runs along the Strip itself, but nothing rail-based reaches outside it, so getting anywhere off the Strip means a car, taxi, or rideshare. Summers are extremely hot and dry.

The Mile High City
Denver sits exactly a mile above sea level where the Great Plains meet the Rocky Mountains, a compact downtown ringed by wide, flat suburbs. It is the gateway to the mountains for skiing and hiking, and much of its draw is what lies a short drive west. The core is walkable and a rail line runs in from the airport, but the wider region runs on the car. The altitude is real, so take the first day easy.

We track the sun along your route
Your flight path is broken into hundreds of points. At each one we check where the sun is and which side of the plane it faces.
You get a recommendation
Which side of the plane to sit on, left or right, depending on whether you'd rather avoid the sun or enjoy it. The percentages and the map are there if you want to see why.

Notes from the product.
Small updates, route observations, and clearer explanations for how the app keeps evolving.
Type less, wait less, wonder more
Airport search now understands metro codes and old city names, FlightSide loads noticeably faster, and a new Feeling lucky button chooses a flight for anyone without one in mind.
A closer look at the route, not just the seat
FlightSide now shows the two cities and key details about the flight alongside the seat recommendation: confirm you picked the right airports, read the time change off two clocks, and check the return leg.
It's all about the sun (after all)
Not all sunlight reaches the side windows. FlightSide now weighs the sun’s angle to the cabin and shows twilight along the route.
