Light Rail Options: Take the A Line train directly from Union Station to Denver Airport
The A Line train offers a seamless, stress-free connection between Denver Union Station and Denver International Airport (DEN), making it the most direct public transit option available. Operating daily from approximately 3:30 AM to 12:30 AM, the A Line runs every 15 minutes during peak hours and every 30 minutes during off-peak times. This frequent service ensures travelers can easily align their schedules with flight times, eliminating the need for rushed transfers or lengthy waits.
To embark on this journey, begin at Denver Union Station, a historic transportation hub located in the heart of downtown. Purchase a ticket at the station’s vending machines or use the RTD Mobile Ticketing app for added convenience. A one-way fare to the airport costs $10.50, and the trip takes approximately 37 minutes, covering 23.5 miles. The train’s spacious interiors accommodate luggage, and dedicated racks ensure your belongings remain secure throughout the ride.
Comparatively, the A Line stands out for its reliability and efficiency. Unlike rideshares or taxis, which can be affected by traffic congestion, the light rail operates on a dedicated track, bypassing road delays. Additionally, it’s a more cost-effective option than private transportation, especially for solo travelers or small groups. For those concerned about sustainability, the A Line reduces carbon emissions, offering an eco-friendly alternative to driving.
Practical tips for a smooth experience include arriving at Union Station at least 10 minutes before departure to account for ticket purchase and boarding. If traveling during peak hours, consider securing a seat near the luggage racks for easier disembarkation. For late-night or early-morning flights, verify the train schedule in advance, as service frequency decreases after 7 PM. Finally, familiarize yourself with the airport’s layout: the A Line arrives at the Denver Airport Station, conveniently located near the Jeppesen Terminal, with easy access to all concourses via a short walk or shuttle.
In conclusion, the A Line train is a standout choice for travelers seeking a direct, affordable, and efficient route from Union Station to Denver Airport.

Taxi or Ride-Share: Use Uber, Lyft, or a taxi for a quick, direct trip
For travelers seeking a seamless journey from Union Station to Denver International Airport, opting for a taxi or ride-share service like Uber or Lyft offers unparalleled convenience. These services eliminate the need to navigate public transit schedules or shuttle stops, providing a direct route to your terminal. Simply step outside Union Station, request a ride through your preferred app, and within minutes, you’ll be on your way. This option is particularly ideal for those with heavy luggage, tight schedules, or a preference for privacy and comfort.
While the cost of a taxi or ride-share is typically higher than public transportation, it’s a predictable expense, especially during off-peak hours. Prices can range from $35 to $60, depending on traffic and demand. To maximize savings, consider scheduling your ride during non-rush hours or using fare-estimate tools within the apps. Additionally, pooling services like Uber Pool or Lyft Shared Rides can reduce costs by pairing you with other passengers heading in the same direction, though this may add slight detours to your trip.
One of the standout advantages of this option is its flexibility. Unlike trains or shuttles, which operate on fixed schedules, taxis and ride-shares are available 24/7, making them a reliable choice for early morning or late-night flights. For added peace of mind, most ride-share apps allow you to track your driver’s arrival in real-time and share your trip details with loved ones. This transparency ensures a stress-free start or end to your journey.
However, it’s essential to plan for potential delays, especially during peak travel times or adverse weather conditions. Traffic congestion along Interstate 70 or Interstate 25 can extend travel times, so allow a buffer of at least 45 minutes to an hour for the 25-mile trip. If you’re traveling during snowstorms or rush hour, consider booking your ride earlier than usual to avoid last-minute scrambling.
In conclusion, choosing a taxi or ride-share from Union Station to Denver Airport is a straightforward, time-efficient solution for travelers prioritizing speed and convenience. By understanding the cost dynamics, leveraging app features, and accounting for potential delays, you can ensure a smooth and hassle-free transfer. Whether you’re a solo traveler or part of a group, this option adapts to your needs, making it a top choice for airport transportation.

Shuttle Services: Book airport shuttles offering affordable shared rides from Union Station
For travelers seeking a cost-effective and hassle-free way to reach Denver International Airport (DEN) from Union Station, shuttle services emerge as a standout option. These shared rides balance affordability with convenience, making them ideal for budget-conscious individuals or groups. Unlike private transfers, shuttles pool passengers heading in the same direction, significantly reducing costs while maintaining a structured schedule. This model not only eases financial strain but also minimizes environmental impact by consolidating trips, aligning with Denver’s eco-conscious ethos.
Booking a shuttle from Union Station to DEN is straightforward, with multiple providers offering online reservations. Popular services like SuperShuttle and Groome Transportation allow passengers to secure seats in advance, ensuring availability even during peak travel times. Most shuttles operate on fixed routes with designated pick-up and drop-off points, streamlining the journey. For instance, Groome Transportation provides hourly departures, with travel times averaging 45 minutes depending on traffic. Pro tip: Book at least 24 hours ahead to guarantee a spot and avoid last-minute surges in pricing.
While affordability is a key draw, shuttle services also prioritize comfort and reliability. Vehicles are typically spacious, offering ample legroom and storage for luggage. Many shuttles include amenities like Wi-Fi and charging ports, catering to travelers who need to stay connected. However, it’s important to note that shared rides mean slightly longer travel times due to multiple stops. To mitigate this, plan to arrive at Union Station at least 15 minutes before departure and allow extra buffer time for airport security.
Comparing shuttle services to alternatives like taxis or rideshares highlights their value proposition. A one-way shuttle fare averages $25–$30 per person, significantly lower than the $60–$80 cost of a private Uber or Lyft. Even public transit, while cheaper, lacks the door-to-door convenience and luggage assistance that shuttles provide. For families or groups, some providers offer discounted rates, further enhancing the cost-effectiveness of this option.
In conclusion, shuttle services from Union Station to Denver Airport are a smart choice for those prioritizing affordability without sacrificing comfort. By booking in advance, understanding the shared ride dynamics, and planning for potential delays, travelers can enjoy a stress-free journey to their destination. Whether you’re a solo adventurer or part of a larger party, shuttles offer a practical solution that combines value, convenience, and sustainability.
