Travel Tips
To make your journey from Atlanta to Denver as smooth as possible, consider several key factors before heading to the airport. First, because Denver is situated at exactly 5,280 feet above sea level, it is vital to start hydrating long before you land to mitigate the effects of altitude sickness once you arrive in the thinner air. Second, keep in mind that Denver’s weather can change rapidly; even if it is a sweltering ninety degrees in Atlanta, you should pack a versatile jacket for Denver's unpredictable evening temperatures. Third, since both ATL and DEN are massive airports with significant walking distances between gates, wear comfortable shoes and arrive at least two hours early to navigate security and transit systems comfortably. Finally, download your airline's mobile application ahead of time to track gate changes and baggage status in real-time, as gates in both hubs can be subject to last-minute adjustments.
