What the Risk Score Means
Every flight gets a live assessment based on visibility, ceiling, and wind at KASE — calibrated to the Embraer E-175 (E175), the most common commercial aircraft type flying in and out of Aspen, operated by United and Delta.
🟢 GREEN — Low Risk
Conditions are favorable. E175 flights typically operate normally.
🟡 YELLOW — Moderate Risk
Conditions where delays, weight limits, or diversions are more likely. Monitor closely.
🔴 RED — High Risk
Near operational limits. Diversion or cancellation risk is meaningfully higher.

Frequently Asked Questions
Who is this best for?
Anyone who travels in and out of Aspen and has felt the pain of delays, diversions, or wasted trips. That includes locals, visitors, second homeowners, business travelers with tight schedules, and event coordinators.
How accurate is the risk score?
The score is based on live weather data from the US government — the same official source airlines use. It's a passenger-level heuristic calibrated to E175 operational limits at KASE. It won't match an airline's exact decision-making, but it's a reliable early indicator of when conditions are trending toward delays or diversions.
How far in advance can I see risk?
The free tool shows the current plus forecast periods, typically covering up to 30 hours ahead. Premium alerts will notify you as soon as conditions change within that window — so you have time to act before the airline does.
When will Premium launch?
We're targeting Summer 2026. Waitlist members will be notified 2 weeks before launch and get early access.
How do the alerts work?
You'll receive email notifications when risk at KASE shifts from GREEN → YELLOW or RED. SMS alerts are reserved for critical (RED) conditions or rapid deterioration — so you only get a text when it really matters.
What if I'm not satisfied?
We offer a 30-day money-back guarantee. If Premium doesn't help you make better travel decisions, we'll refund you — no questions asked.
Why is the risk score based on the Embraer E-175?
The E-175 is the most common commercial aircraft type flying in and out of Aspen — it's the plane United and Delta operate on routes to Aspen. Because it's the aircraft most passengers are actually on, we calibrate our visibility, ceiling, and wind thresholds to its known operational limits at KASE. If the E-175 is likely to have trouble, you're likely to have trouble.
American Airlines more often flies a smaller CRJ-700 aircraft to Aspen, which has slightly tighter limits. So if you're on an AA flight, you can consider the E-175-based risk score a conservative estimate — if it says YELLOW or RED, your CRJ-700 flight is at even higher risk.
Is this official airline information?
No. This is a passenger-focused risk assessment tool using official weather data (NOAA METAR/TAF). Airlines make their own operational decisions based on many additional factors including aircraft weight, crew, runway conditions, and company policies.
That being said, you'll likely have this information before the airline tells you that your flight is delayed or canceled — giving you a critical early warning so you can make informed decisions about when to book, whether to head to the airport, or if you should consider alternative plans.
