When does something other than flying beat ORD–DEN?
Driving Chicago to Denver is a multi-day stamina test — flying wins on time for almost all city trips. Amtrak’s California Zephyr exists but is a multi-day journey, not a substitute for a same-week city trip. Flying via a third hub rarely helps unless a sale fare is dramatic.
