Why we built this
OnlineCheckIn is a free directory of every airline's official check-in URL, built on top of three things big travel sites don't bother with:
- Live operational data — security wait times crowdsourced from real travelers, updated every 30 minutes.
- Disruption recovery — when your flight is delayed or cancelled, we walk you through your EU 261 rights and help you claim compensation.
- Carbon transparency — every route shows CO₂ per passenger and a train alternative where one exists.
No accounts. No paywalls. No premium tier. Just the fastest path between you and your flight.
