Travel Tips
First, stay hydrated to combat altitude sickness; moving from the humid climate of Austin to Denver’s high altitude (5,280 feet) requires drinking plenty of water before and during your flight. Second, since Denver is a major hub for Frontier and United, booking at least three to four weeks in advance often yields the most competitive rates, especially during the peak winter ski season. Third, if you are flying with outdoor gear like skis or snowboards, verify the baggage policies of your specific airline, as some carriers offer seasonal waivers while others charge standard oversized fees. Finally, consider using the A-Line commuter rail from DEN to Union Station, as it is a far more affordable and efficient way to reach downtown Denver compared to expensive rideshares.
