For longer term storage, there are many self storage units around the metro area. Not cheap, but then neither is paying extra baggage fees and lugging around extra stuff not needed for another leg of your trip, as it sounds like Terry might be doing. For example, I found "Downtown Denver Self Storage" with units starting at $45 a month. http://www.downtowndenverstorage.com/
Now that you’ve scored yourself some Denver luggage storage, the next thing on the list is finding things to do and places to explore. If it’s a Monday, a lot of the amazing indoor attractions and restaurants will be closed, but there is still plenty to do on any day of the week! See a concert at the Red Rock Amphitheatre, marvel at the beauty of the Cathedral of the Immaculate Conception or take a hike in the famous Rocky Mountains. You won’t regret it!
There are two safes in the RPD--one in the West Office and the other in the Waiting Room. Both yield valuable resources well worth grabbing. We won't spoil what's inside each here (spoiler: they're all useful items), but we will reveal how to open them. The safe solutions are found in memos scattered around the building, which we've detailed the locations of for all of you completionists out there.
With the same standard features as the Traditional line, the Traditional Plus Collection is intended for more rugged applications. Plastic Lockers are ideal for high-humidity moisture applications, as these virtually maintenance-free lockers will never rust, rot or corrode. These lockers are available in multiple configurations and are backed by a 15-year warranty.
There are plenty of convenient places to store your luggage in Denver, from downtown to Lincoln street to Capitol Hill and Commons park. The cost is just US$6 per day, and check in time is just 3 minutes. So basically, in the same time it took to make that instant cup of Ramen before rushing to the airport, you can be in and out the door with no luggage to weigh you down.
Terry, there are many storage unit places closer to the airport, but then of course you'd have to rent a car. DIA Self Storage, for example, is less than 10 miles away. You can google map Denver International Airport, then "search nearby" for "self storage units" if you think that's something you might want to do. http://www.coloradoselfstorage.com/

Dimensions (Note that, in English-speaking countries, even those commonly using metric measurements now, locker dimensions are usually clean numbers of inches or feet, while the corresponding metric measurements are uneven, involving decimal places when precision is required, presumably resulting from continued use of locker designs based on feet and inches, unchanged for decades other than for cosmetic features.):
