Show HN: TripCoral – Free itinerary and live updates from public flight data
When TripCase shut down, I couldn't find an Android or web replacement I actually liked using. Especially with live flight tracking for gate and delay notifications. So I built TripCoral. Airports and aviation authorities actually give out a lot of FIDS and air-traffic data for free: Avinor (Norway), Swedavia (Sweden), Schiphol (Netherlands), FAA SWIM (United States) etc. Instead of paying a commercial data broker, I wrote a Go collector that pulls from 100s of feeds covering ~1900 airports.

Version & cost evidence
Source votes: 2 votes (Nov 12, 2026 UTC; cumulative since publication); previous same-scope observation: 1 (Nov 12, 2026 UTC). These observations do not establish demand growth. Recent records to compare: “Show HN: Mandaboard, privacy-focused kindness trove, CBT log and vision board” (Show HN, Nov 11, 2026); “Show HN: I checked 66 AI tools' privacy policies for AI training” (Show HN, Nov 10, 2026). Shared themes are navigation hints; they have not been verified as the same need or independent corroboration.
Who is affected
Identify the existing workflow this change affects before recommending an upgrade. Launch attention does not establish improvement; an API, pricing or availability change may instead create migration work.
Missing comparison points
Missing checks: old versus new behavior, affected plans and regions, availability date, compatibility, rollback path and cost under the same workload.
Migration check
Save the release or policy notice, run the same task on the old and new option, and compare outputs and the full bill. For retirement notices, verify the deadline before scheduling migration.
