LayoverLens

The Problem

Frequent travelers and airline employees on r/solotravel and r/travel regularly ask for help turning 4–14 hour layovers into mini-city experiences, but existing tools either give generic tourist lists or ignore transit visa restrictions and re-entry rules. LayoverLens takes a traveler's passport nationality, layover airport, and duration, then generates a tailored itinerary of only what's actually reachable — accounting for visa-on-arrival eligibility, transit visa rules, terminal re-entry buffer time, and real transit durations from the airport.

Target Audience

Business travelers and long-haul backpackers with layovers of 3–16 hours who want to leave the airport safely

Monetization Angle

Freemium: 3 free itinerary generations; $3.99 one-time 'Layover Pack' per airport or $19/yr unlimited for frequent flyers

Recommended Tech Stack

Why Now

Long-haul flight bookings have rebounded to record highs in 2024–2025 and hub airports are actively marketing layover tourism, creating audience awareness but no quality tool.

MVP Scope

User enters passport country, airport code, and layover duration; app outputs a ranked list of 3 reachable activities with visa eligibility flag and transit time back to gate.

AI Angle

GPT-4o synthesizes visa eligibility rules, real transit times, and local attraction data into a coherent narrative itinerary with time-stamped steps rather than a raw list.

Primary Risk

Transit visa rules change frequently and errors could cause passengers to be denied re-entry — accuracy and liability disclaimers are critical, and data maintenance is ongoing.

Validation Checklist

• Search r/solotravel and r/travel for 'layover' posts from the last 6 months and catalog the top 10 airports most frequently asked about.
• Build a static itinerary page for Dubai (DXB) 6-hour layover and share it in r/solotravel to measure upvotes and saves as demand proxy.
• Run a $15 Google Ads test targeting 'things to do during layover in [city]' keywords to measure cost-per-click and intent.
• Interview 5 frequent flyers who have done a layover city-exit in the past year to validate pain points around visa confusion and time anxiety.

Who Would Pay For This

Likely buyers are people already trying to solve this problem with manual workarounds. Start with Business travelers and long-haul backpackers with layovers of 3–16 hours who want to leave the airport safely and validate urgency before adding secondary features.
