People still pay for Seats.aero because travel subscriptions sell current data and confidence during disruption, not just an itinerary list. The recurring cost buys map licensing, fare feeds, reservation access, route freshness, disruptions, geocoding, caching, offline data, and support, not just the visible interface.

what AI can build
Save and compare user-entered award availability, map places and reservations, and keep an offline itinerary without crawling airline systems or claiming live proprietary availability.
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Seats.aero, save and compare user-entered award availability without crawling airline systems. The hard boundary is large award-availability dataset, alerts, route tools, and continuous collection, plus proprietary live data and network coverage.

the prompt
Catalog estimateBuild a closest honest personal substitute for Seats.aero in an empty repository. Use Next.js 15, TypeScript, SQLite, MapLibre GL, and user-supplied map and travel APIs; do not offer alternative stacks. The core loop is: save and compare user-entered award availability, map places and reservations, and keep an offline itinerary without crawling airline systems or claiming live proprietary availability. Make the first run work locally with one documented command. Store all user data locally by default and make export straightforward. Put secrets in .env, ship .env.example, and never commit credentials. Create trips, days, places, reservations, notes, documents, packing items, and emergency contacts. Geocode only user-entered places and display them through MapLibre with cached trip-area tiles where allowed. Parse forwarded reservation text locally into editable fields without logging message content. Build a day timeline, route overview, conflict warnings, timezone display, and offline printable itinerary. Allow manual updates for delays and reservations and label all external data with source and timestamp. Export a complete trip bundle as JSON, calendar file, Markdown, and PDF. Include clear empty, loading, success, and recoverable error states. Add input validation, safe filenames, and graceful handling of unavailable APIs. Write focused tests for the core transformation and one end-to-end happy path. Create a README with setup, architecture, permissions, data location, and backup steps. Do not add accounts, billing, telemetry, analytics, or a hosted control plane. Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure. Deliberately leave out live flight, hotel, award, or ticket inventory. Deliberately leave out commercial turn-by-turn navigation and global offline maps. Deliberately leave out booking guarantees, disruption rebooking, and traveler support. Finish by running the tests and listing the exact commands used.

questions
Can AI replace Seats.aero?
Not really. Seats.aero's value is not just interface code — proprietary live data and network coverage. See the honest breakdown above.
How much does Seats.aero cost?
Seats.aero is listed at about $9.99/month (Pro, checked 2026-07-31), or $119.88 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.
What do I lose by replacing Seats.aero?
Honestly: large award-availability dataset, alerts, route tools, and continuous collection; live fare and inventory data; global routing dataset; crowdsourced trail intelligence; booking, disruption support, and offline map fleet. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to Seats.aero?
Yes — Wanderer (Open-source self-hosted trail database and route explorer using open map data.). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
