Wikipedia says:

Denver International Airport uses many pneumatic tube systems, including a 25 cm diameter system for moving aircraft parts to remote concourses, a 10 cm system for United Airlines ticketing, and a robust system in the parking toll collection system with an outlet at every booth.

Note: No citation, and I can't find any reference to it on the web.

Question: If these systems actually exist, what are their total lengthes (eg. 35 km total) and usage rate (eg. 7000 objects per day)?

References appreciated.

  • $\begingroup$ There’s a bit of info here: expo1000.com/parking/press/20000322.htm mainly about the cash handling system for the toll booths, but it says all the systems were built by the same company. $\endgroup$

    $\begingroup$ Have you considered just asking Denver Airport on Twitter, or whatever their preferred social media platform is? There are a few web references from when the airport was about to open (here, here) but nothing recent, and the provider's site doesn't mention the airport at all. It looks like the system certainly was there, but I can't find any recent link that confirms it still is there. $\endgroup$

    $\begingroup$ @Federico No, but it's a good option if no one here can find a clear reference. And if the OP does ask them, he can always come back and answer his own question. $\endgroup$

According to the Public Relations Department at the Denver International Airport, as of May 24, 2019 there is no such pneumatic tube system at the airport.

Hello Juan,

Thank you for contacting Denver International Airport. We have evaluated your email. I spoke with airport operations to find out if they had any information on using a pneumatic tube system and they advised me they do not. We do appreciate your feedback.

Thank you, kindly, for bringing this matter to our attention.

Warm Regards,

Flydenver Team Meseret
