Airport information

Which Denver airports are included?

This page searches DEN — Denver International Airport. Airport coverage follows the destination city market in the passenger dataset, with minor airports excluded. Always check the airport code on both legs: a city search can include different arrival airports, and the cheapest option may not be closest to where you are staying.

GOOD QUESTIONS. STRAIGHT ANSWERS.

Before you take off for Denver.

What is the cheapest flight to Denver you have recorded?

The lowest seven-night round-trip search fare in our archive is $152, recorded Sep 27, 2026 for ORD to DEN, Dec 2–Dec 9, 2026. Our route archive starts Sep 27, 2026. This is our observed record, not an industry-wide all-time low, a verified booking price or a current offer.

How much are cheap flights from Chicago to Denver?

Our lowest current seven-night sample is $152 round trip for one adult in economy, from ORD to DEN, Dec 2–Dec 9, 2026. It was checked Sep 27, 2026. This is a dated search result, not a guaranteed ticket price; confirm the return and full fare conditions before paying.

Is O’Hare or Midway cheaper for Denver?

For the matched Dec 2–Dec 9, 2026 search, ORD had the lowest sample at $152. The highest and lowest airport fares were $52 apart. That applies to those dates and settings only. Try other matched dates and add your own ground transport cost in the airport calculator above.

Can I fly nonstop from Chicago to Denver?

The current sample includes a nonstop outbound from ORD to DEN on Dec 2, 2026, with a round-trip search fare of $152. Check the return direction separately: a nonstop outbound does not guarantee a nonstop return.

What is the cheapest month to fly to Denver?

The travel-period chart compares only the dates we sampled. It cannot establish the cheapest month of the year. Start with a promising sampled period, then check nearby dates with the same trip length. The separate history chart tracks one specific search over time; it is not a travel calendar.

Which Denver airport should I choose?

This destination market includes Denver International Airport (DEN). Check the exact arrival code on the fare you choose, then compare the onward journey to your accommodation. The arrival section links airport information and our source-backed planning notes.

Will Skyscanner show the same price as Google Flights?

Not necessarily. The buttons open separate searches with matching airports and dates when a dated sample is available. Providers can show different airlines, sellers, baggage rules and live prices. The sampled Google Flights price is never a Skyscanner quote.

Are bags, hotels and rental cars included?

Do not assume bags are included unless the provider explicitly confirms them. Our research shows flight search fares; the accommodation and rental-car links are separate planning tools. Compare the final total, cancellation terms and location before booking any part of the trip.

Answers use the dated research and sources on this page. Read our flight-saving field notes for a broader planning checklist.
