The biggest discount: choosing off-airport over DIA
The largest single discount available at Denver Airport isn't a coupon code — it's simply choosing an off-airport lot over DIA's own facilities. Off-airport lots start at $9/day vs DIA's $13/day Economy lot — a 31% discount before any program. Vs the DIA covered garage ($28/day), off-airport covered lots are 36–57% cheaper.
