Boulder AB Bus from Denver DIA

Visiting friends in Boulder? There's an easy way to get there from Denver Airport. The RTD's AB SkyRide bus. I found the RTD's website a little confusing so I thought I'd document the trip here. 

The AB bus is $13 each way which can be paid with exact change to the driver. There is also a round trip option for $24 that can be paid by credit or debit card from the RTD desk inside the terminal. For some reason, you cannot buy paper one-way tickets with your card - round trip only. 

The RTD desk is inside the center of the main terminal.



Once you purchase your ticket head upstairs and look for door 605. (Currently due to construction they are only using the east side pick up location - thanks to Alek in the comments.) Once outside that door, cross the street to the island where the RTD boarding signs are. You can find the bus schedule on the RTD website





Once the AB bus arrives, you can insert one of your purple tickets directly into the dollar bill slot on the bus money collector.

And, of course you'll have to find a seat before the inconsiderate TSA agents, just getting off their shift but still in uniform, spread out over two seats and pretend to sleep. All at 2pm in the afternoon.  Their professionalism knows no bounds.

As a long-time resident of the Republic of Boulder, the AB bus is a great way to get to/from the airport.

Nice writeup Michael ... but an FYI add that due to construction on the west side of the airport, the bus pickup is on the East side only. Once all that is done, it should return back to both sides ... and probably back to Level 5 ... which is where you come out from security.

Thanks Alek! I updated the post to mention the construction.

I don't believe that the construction affecting the bus system at the airport is still going on. You may want to verify whether the bus pickup location has reverted since Alek's last post in 2013.
