What factors are causing Alaska Airlines's on-time arrival performance to decline by 8% on West Coast routes in the last month?

Introduction

Alaska Airlines' 8% decline in on-time arrival performance for West Coast routes over the past month is a critical issue that demands immediate attention. This analysis will systematically identify, validate, and address the root causes while considering both short-term and long-term implications for the airline's operations and customer satisfaction.

I'll approach this problem by first clarifying key details, ruling out external factors, understanding the product ecosystem, breaking down the metric, gathering relevant data, forming hypotheses, conducting root cause analysis, and finally proposing validation methods and solutions.

Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be seasonal factors at play. Has there been any unusual weather patterns on the West Coast recently?

Why it matters: Weather can significantly impact flight schedules. Expected answer: Information about recent weather conditions. Impact on approach: If weather is a factor, we'll need to consider both short-term mitigation and long-term climate adaptation strategies.

• Considering the specificity of the decline, I'm wondering about recent changes in operations. Have there been any significant operational changes in the last 1-2 months?

Why it matters: Internal changes could be disrupting established processes. Expected answer: Details of recent operational changes, if any. Impact on approach: If changes have occurred, we'll focus on change management and process optimization.

• Given the focus on West Coast routes, I'm curious about airport-specific issues. Are there particular airports or routes showing more significant declines than others?

Why it matters: Localized issues might require targeted solutions. Expected answer: Breakdown of performance by airport or route. Impact on approach: If specific locations are problematic, we'll prioritize those for immediate action.

• Thinking about the broader context, I'm interested in industry trends. How does this 8% decline compare to Alaska Airlines' historical performance and current industry benchmarks?

Why it matters: Understanding if this is an isolated issue or part of a larger trend. Expected answer: Comparative data on historical and industry performance. Impact on approach: If it's an industry-wide issue, we'll need to consider competitive positioning and industry best practices.
