BOS to DEN: Find the Best Deals on Flights from Boston to Denver

1. Hydration is Key: Denver sits at exactly 5,280 feet above sea level, and the change in altitude can be jarring if you aren't prepared. Start drinking extra water during your flight from Boston to help your body acclimate to the thinner, drier mountain air immediately upon landing. 2. Transportation Options: While Logan is easily accessible via the Blue Line or Silver Line, Denver International Airport is quite far from the actual downtown area. Consider taking the A-Line commuter rail from the airport to Union Station for just $10.50, which is often significantly faster and cheaper than a ride-share during peak traffic hours. 3. Layering Clothes: Even if it is a humid summer day in Massachusetts, Denver’s weather can fluctuate wildly within a single afternoon. Always pack a light jacket or sweater in your carry-on, as evening temperatures in the Rockies often drop significantly once the sun goes down, even in July.

Flight prices for the Boston to Denver route tend to fluctuate significantly based on the winter ski season and summer hiking peaks. Generally, the most expensive times to fly are during the winter holidays and spring break months when travelers flock to the mountains for outdoor sports. Conversely, you can often find the cheapest fares during the 'shoulder' months of October, November, and April, when the weather is transitioning and the demand for outdoor recreation is slightly lower than the peak summer or winter surges.
