Compare your options

Choose for the real itinerary

Best general choice

RTD A Line

Follow airport signs to Denver Airport Station, check the westbound schedule and ride toward Union Station. Select an earlier station only when it improves the final connection.

Best door to door

Taxi or ride app

A direct vehicle can help with groups, luggage, mobility constraints or addresses far from rail. Road conditions and pickup rules can change.

For onward driving

Rental car

A rental may make sense for a broader Colorado itinerary, but downtown parking and mountain-weather requirements belong in the full cost and risk check.

Build the trip

Step by step

  1. Open the current A Line westbound schedule and alerts.
  2. Follow signs from the terminal to Denver Airport Station.
  3. Purchase or activate the current airport fare using RTD instructions.
  4. Secure luggage without blocking aisles or exits.
  5. At Union Station, follow the planned walk, transit or short vehicle connection.

Practical planning

Make the route work door to door

Planning check 1

Union Station is the central rail endpoint, not the correct final stop for every Denver address.

Planning check 2

Weather can affect rail, roads and airport walking conditions.

Planning check 3

Do not reuse the Boulder AB1 instructions on this city route; A Line owns the direct downtown intent.
