Product design question

Design a product to be used in airports.

What this question tests

Basic product design for a high-stress, time-constrained environment, requiring the candidate to identify a specific traveler pain point.

Pick a specific user and moment, like a traveler navigating security and gate-finding under time pressure, rather than 'airport travelers' broadly.
Name the core pain point: uncertainty about wait times (security, immigration) and real-time gate/walk-time information causing stress and missed flights.
Propose a focused feature: a live, crowd-sourced or sensor-based wait-time estimator for security lines combined with a personalized 'time to gate' countdown based on the user's current location in the airport.
Consider monetization: partnership with airport retail/dining to surface relevant offers during confirmed downtime (when the wait-time tool shows the user has slack).
Define success as reduction in reported missed-flight incidents (via survey) and feature usage rate during active trips.

Anchors on the single highest-stress airport pain point, time uncertainty, rather than a generic 'airport info app.'
Proposes a real-time, personalized mechanism (location-based gate countdown) instead of static airport information.
Names a business angle (retail partnerships during confirmed downtime) consistent with airport commercial models.

Designing a static information app (maps, terminal directory) with no real-time, personalized component.
No success metric tied to the actual stress/risk being solved, missed flights or excessive wait uncertainty.

How would you get accurate real-time security wait-time data without airport cooperation?
How would you handle this working across many different airports with different layouts and systems?
