By the time you find out, it's already news.
Watchlist tracks the aircraft and routes you care about and flags them the moment activity moves — so the signal reaches you while it's still worth something.
You're checking manually, and only when you remember to.
There's a set of tails and routes you care about. Right now, keeping up with them means remembering to check — and you find out what they did days or weeks after they did it, if you catch it at all.
The activity that mattered already happened by the time it crosses your screen.
The signal is only valuable while it's fresh.
A spike you flag a week late isn't intelligence — it's history. The unusual movement your committee should have seen surfaces in a headline instead of in your briefing. The entire value of watching a tail is knowing before the rest of the market does.
First is the only position worth holding.
Every day you're checking by hand is a day the signal can pass while you're looking elsewhere.
In this work, being second is being wrong. The advantage of monitoring decays by the day: the moment activity becomes public, it's worth nothing to the person who was meant to catch it early.
The alert comes to you, because the signal won't keep.
Watchlist flips the work — it watches, and tells you. Pick the tails and routes that matter and Watchlist monitors them against the live data, flagging the moment activity moves, on the same cited methodology behind everything CSI publishes.
Track what matters
Specific aircraft or routes — you choose what's worth watching.
Alerts on movement
The moment activity shifts — activity spikes, unusual runs, efficiency drift, return-to-service and corridor spikes — not weeks later.
Built on live data
The same cited dataset behind CSI — so an alert is a fact, not a rumour.
Be first
Know before it's public — not informed after the fact by someone else's byline.

What being told first actually looks like.
Every watched tail and route, monitored against the live data — flagged the moment it moves, ranked by severity, with a link straight to the full profile. These are real detections on a sample watchlist, by the same engine behind every CSI deviation signal.
Sample watchlist · signals from the same active-peer deviation engine as /tailcheck and the Spikes explorer · dataset refreshes daily.
What it costs to keep checking by hand.
Stay manual and you're choosing to be second. You can't get a missed moment back — and on the manual path, missing them is a matter of when, not if.
Every story that broke without you, every flag you raised after it was already too late to matter.
The signal in your inbox while it's still worth something — and silence on everything that isn't.
Watching is built into Pro.
Watchlist isn't a separate subscription — it's included with CSI Pro and above, alongside full query access to the dataset it monitors. Set a list, choose how you're alerted, and let the signal come to you.
