Clarifying Questions (3 minutes)

• I'm noticing the focus on Heathrow specifically. Has this decline been observed at other airports British Airways operates from?

Why it matters: This helps isolate whether the issue is Heathrow-specific or a broader operational problem. Expected answer: The decline is primarily at Heathrow. Impact on approach: If Heathrow-specific, we'll focus on local factors; if widespread, we'll consider systemic issues.

• Considering the timing, I'm wondering about any recent changes in Heathrow's operations. Have there been any significant alterations to airport procedures or infrastructure in the past 1-2 months?

Why it matters: Recent changes could directly impact departure times. Expected answer: Some minor procedural updates, but no major changes. Impact on approach: If significant changes occurred, we'd prioritize analyzing their impact.

• Looking at the metric itself, has there been any change in how "on-time departure" is defined or measured recently?

Why it matters: Ensures we're comparing apples to apples in our analysis. Expected answer: No changes to the definition or measurement. Impact on approach: If changed, we'd need to recalibrate our analysis based on the new definition.

• Considering potential internal factors, have there been any notable changes in British Airways' staffing, fleet, or scheduling practices at Heathrow in the past month?

Why it matters: Internal changes could significantly impact departure performance. Expected answer: Some normal seasonal adjustments, but no major overhauls. Impact on approach: Significant internal changes would shift our focus to these areas.
