The boarding experience was okay. The dietary food choices were limited, the midway snacks were hard and dry. The seat was uncomfortable - stiff seat cushion, seat back kept springing back to the upright position, narrow seat width. Love the app and the ability to track my luggage. Flight crew was efficient.

FAQs about flying to Colorado

Colorado climate

Coloradans claim their weather is perfect. The state averages 296 sunny days a year. There isn’t much precipitation in the lower elevations, but huge amounts of snow in the mountains.Winter starts in late November and, depending on the snow depth, and lasts into April. In Denver and Colorado Springs, summer days are hot and dry and the evenings mild. Summer comes to the mountains in June, and the warm weather lasts until mid-September. Winter hits around mid-November, though snowstorms can start in the mountains in September.The climate from one area to another can be dramatically different due to the difference in elevation and the orientation of mountain ranges and valleys.

Getting around Colorado

Denver is a transportation hub for Colorado, both for entering and leaving the state and for finding transportation to other Colorado destinations. For a stay in Denver, you can rely on public transportation. Taxis and shuttles are also available in other large cities and towns. To help you get around the state, there are commuter airlines and shuttle buses from the Denver airport. Amtrak has a couple of routes through the state, and some say the Durango and Silverton Narrow Gauge Railroad in the southwest isn’t to be missed.

Getting around the state usually involves a car to some extent, and with visitor centres statewide, you have little trouble getting directions and tips on getting from one place to another.

A world-renowned destination for cyclists, interstate highway shoulders are open to cyclists (except in urban areas). The mountain roads are more demanding, and one of the most popular and challenging routes is the Million Dollar Highway.
