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. The DIA 61st & Peña lot is now $8/day (effective May 14, 2025, via RTD A-Line) and Pikes Peak/Longs Peak are $10/day. Vs the DIA covered garage ($35/day, effective May 2025), off-airport covered lots are 49–61% cheaper. Source: flydenver.com
