The captain just came on the intercom. The weather at Aspen has dropped below safe landing limits, and your flight is being diverted. You'll be landing instead at Eagle, Grand Junction, or maybe Denver. So now what?

Take a breath. This happens often at Aspen, and the airline that flies almost every commercial route into ASE has a well-practiced playbook for it. This guide walks through exactly what to expect once you land, how to get to Aspen from each of the three most common diversion airports, what the airline will and won't do for you, and what your rights are.

First, Here's What Usually Happens

Almost every scheduled commercial flight into Aspen-Pitkin County Airport (ASE) is operated by SkyWest Airlines under one of three brands: United Express, Delta Connection, or American Eagle. (Read why only two specific aircraft types fly to Aspen if you're curious.) Because SkyWest handles essentially all of ASE's commercial traffic, they have what their own leadership has called a refined diversion plan, including contracted bus service back to Aspen from each of the main diversion airports.

In other words, when your flight diverts, there's usually a plan. The question is which version of the plan applies to your situation. Most of the time, one of these three things happens:

  1. You land, you get on a bus, you arrive in Aspen the same day. Most common when the divert lands at Eagle or Grand Junction, and when ASE weather is clearing.
  2. You land, the airline rebooks you on a new flight to Aspen (sometimes the same day, sometimes the next day). More common when the divert lands at Denver, since Denver has frequent direct service to ASE.
  3. You land, you're on your own (the airline cancels the rest of the trip and refunds you, or rebooks you home). This happens during major weather events when no path forward is safe.

The Three Most Common Diversion Airports

Aspen flights divert to one of three commercial airports in Colorado. Here's a quick look at each:

Airport Distance to Aspen Drive time What usually happens
Eagle County (EGE) ~70 miles ~90 minutes Bus to Aspen same day; about 35–40% of ASE diversions
Grand Junction (GJT) ~130 miles ~2.5 hours Bus to Aspen same day; buses often arrive before the plane
Denver (DEN) ~200 miles ~3.5–4 hours Often a rebook or overnight; less common to bus

The choice depends on the weather. Eagle gets roughly 35 to 40 percent of all Aspen diversions because it's closest, but the same weather system that closes Aspen often closes Eagle too. Grand Junction sits on the western slope of the Rockies and usually has different (and drier) weather. Denver is the fallback when the entire mountain region is socked in.

If You're Diverted to Eagle (EGE)

Eagle County Regional Airport, in Gypsum, is the easiest case. It's about 70 miles from Aspen and the drive is roughly 90 minutes via I-70 east through Glenwood Canyon, then south on Highway 82 through the Roaring Fork Valley.

Here's what usually happens:

  • The airline will have a bus. SkyWest's contracted ground transport company is set up to dispatch buses to Eagle on short notice. Listen for gate announcements and watch the airline app. Stay near your gate until you have clear instructions.
  • Plan for a wait. The bus may not leave the moment you land. The airline typically waits for all diverted passengers to deplane before departing. Expect 30 to 60 minutes of waiting after you exit the aircraft, then the 90-minute drive.
  • If you don't want to wait, you have options. Eagle has rental car counters from the major brands (Hertz, Enterprise, Avis, Budget, National), a few private car services, and rideshare (though rideshare is notoriously unreliable for the long mountain drive to Aspen).

If you grab a rental car at EGE

Drop-off in Aspen is usually possible but costs extra. The route is straightforward (I-70 east to exit 116, then CO-82 south for about 40 miles), but in winter or during storms, expect slow traffic, snowpack on the road, and the possibility of CO-82 closures over Independence Pass (closed entirely in winter; you'll always be on the lower-elevation route). Plan an extra 30 to 60 minutes of cushion.

If You're Diverted to Grand Junction (GJT)

Grand Junction Regional Airport is about 130 miles from Aspen, on the western slope. The drive is roughly 2.5 hours via I-70 east, then south on Highway 82. Despite being farther away than Eagle, Grand Junction is a frequent diversion choice because its weather is usually different (and clearer) than Aspen's.

The good news: the airline bus protocol from GJT is well-rehearsed. Reports from passengers and the airport say the contracted buses are sometimes already at the curb when the diverted plane pulls up.

  • Bus is usually the right call. The drive is long but the airline covers it. The bus drops you off at Aspen-Pitkin County Airport, where you can pick up checked bags from the next ASE arrival or arrange ground transport into town.
  • Rental cars are an option, but be aware. GJT has rental counters, but you'll be driving back into the same weather your flight just dodged. The road from Glenwood Springs up Highway 82 to Aspen can be slow and unpredictable in winter.
  • The bus often arrives before everyone is off the plane. Don't dawdle in the terminal. If you need food, grab something quickly. The bus rarely waits long.

If You're Diverted to Denver (DEN)

Denver International Airport is the longest haul, about 200 miles east of Aspen. The drive is 3.5 to 4 hours under normal conditions and significantly longer in winter weather over Vail Pass.

A Denver diversion is a different situation than Eagle or Grand Junction. The airline is less likely to bus you 200 miles. Instead, you'll usually:

  • Be rebooked on the next flight to Aspen. Denver has the most frequent ASE service of any U.S. city, with roughly 8 United Express flights per day. If the weather clears, you can often be on a flight within a few hours.
  • Or be rebooked for the next morning. If you land late in the day or weather is expected to continue, an overnight in Denver is common.
  • Or be offered the choice to drive. The airline can refund the unused leg of your ticket if you'd rather rent a car and drive. This is often the fastest way to get to Aspen if the weather is going to keep grounding flights all day.

About Epic Mountain Express (formerly Colorado Mountain Express)

Many longtime Aspen travelers remember booking shared shuttles to and from Denver on Colorado Mountain Express. CME was rebranded to Epic Mountain Express, and as of recent updates, their service to Aspen, Snowmass, and the Roaring Fork Valley has been suspended. If you've used them in the past, call to confirm current availability before assuming a shuttle option from Denver. Private car services and rental cars remain the most reliable options.

Will the Airline Get Me to Aspen? (And Other Rights Questions)

Weather diversions are considered outside the airline's control. That has specific consequences for what you're owed under U.S. Department of Transportation rules.

What the airline must do

  • Rebook you at no extra cost. If your flight is canceled or if a delay causes you to miss your destination, the airline must put you on the next available flight at no charge.
  • Refund you for unused portions of your ticket. Under DOT rules updated in late 2024, refunds are now automatic for significant itinerary changes. If you decide not to continue the trip, you're entitled to a refund.
  • Get you to your destination if they intend to. If the airline is going to bus you to Aspen, that bus is at no cost.

What the airline is NOT required to do (for weather)

  • Pay cash compensation. Weather diversions are classified as uncontrollable, so airlines are not required to pay compensation beyond your ticket cost.
  • Pay for a hotel. If you're stuck overnight in Denver because of weather, most airlines will not cover lodging. Some may give you a discounted hotel rate as a courtesy. Always ask, but don't count on it.
  • Pay for meals. Same idea. Some airlines provide meal vouchers as a goodwill gesture for long delays. It's worth asking, but not a guarantee for weather.

If your diversion was caused by something other than weather (mechanical issues, crew availability, an airline scheduling problem), you have more rights. The 10 largest U.S. airlines have publicly committed to covering meals and lodging during airline-caused disruptions. Check your airline's customer service plan for specifics.

Practical Tips for Any Diversion

  1. Use the airline app while you're still in the air. If your flight has wifi, open the app and check rebooking options before you land. By the time you land, the entire planeload is competing for the same seats. Being first matters.
  2. Call the airline while you wait in line at the counter. Phone agents and gate agents have the same systems. Whichever one picks up first wins. On hold? Use the time to walk to the counter, and hang up when you reach the front.
  3. Take photos of your bag tags and boarding pass before you board. If your bag goes to Aspen on a later flight and you go by bus, you'll need the tag number to track it down.
  4. If you're on the bus, your bags usually catch up later. Checked bags often stay with the plane, which may continue to Aspen later that day or the next morning. The airline will deliver them to your hotel for free in most cases.
  5. Save your receipts. Even when the airline isn't required to reimburse you, sometimes they will, and sometimes travel insurance does. Keep meal, hotel, and ground transport receipts until you're home.
  6. Stay polite with gate agents. The diversion is not their fault. They have far more flexibility to help you (waive a fee, get you a hotel rate, find a creative rebooking) when you treat them like a human.

How to Know It's Coming Next Time

Most Aspen diversions are weather-driven. The three factors that drive them are visibility, ceiling height (how low the clouds are), and wind. The aircraft that fly to Aspen have specific thresholds for each of these, and when current or forecast conditions are pushing those limits, the chance of a divert spikes.

The KASE Weather dashboard tracks live and forecast conditions at ASE and scores them against the actual operating limits these planes fly to. If you're checking the dashboard a few hours before your flight and it's showing YELLOW or RED, that's a good moment to call the airline about an earlier flight, or to mentally prepare for the possibility of a divert.

For repeat Aspen flyers, KASE Weather Premium can email you ahead of time when conditions shift toward delay or diversion territory, so you have a heads-up well before the airline does.

The Bottom Line

If you've just been diverted from Aspen, the most likely outcome is that you'll get to Aspen the same day. Eagle and Grand Junction diversions almost always end with a bus ride. Denver diversions usually mean a rebooked flight or a rental car. None of these scenarios are fun, but all of them are routine for the airline. Stay calm, use the app, and remember that most Aspen passengers experience at least one divert eventually. It's part of the deal for flying into one of the most beautifully sited (and weather-sensitive) airports in the country.
