Turn your status into a first-class seat.
For road warriors with elite status. A machine learning model scores every flight on your real odds of clearing the complimentary upgrade list — so you book the one that gets you up front, on United, Delta, American, and Alaska.
Start free — your first search shows every flight, no account at all.
Every flight, scored like this.
Schedule, aircraft, open premium seats against cabin size, fare — and the upgrade score: a calibrated probability with its honest range, plus one-tap booking on the airline's own site.
4h 41m · nonstop Airbus A321neo 10 / 20 $486
10 of 20 premium seats open now (~6 expected by departure); you project around #3; modeled from typical elite demand on this route (no waitlist yet) — a real contender — reasonable to book, unwise to count on.
Then the same route, five days at a glance.
Morning, afternoon, evening — every departure scored, so you can see the day that actually clears before you commit to one.
Illustrative example with sample numbers — run a search to see live odds for your status.
The only tool that shows you PZ and PN by name and builds its timing around United's 96-hour complimentary-upgrade window — so you know whether to burn PlusPoints before you spend them. See what we watch on United →
Book the flight that clears.
We can't pull strings to get you upgraded — but booking the same route an hour later can double your odds of clearing the list.
A 70% shot still misses 3 in 10.
Every prediction is a probability, not a promise — and every one is graded against the real gate outcome.
Hopeless flight? We'll tell you first.
When your flight's a long shot, we say so before you book — and point you to a better departure when one exists.
Track it, and we'll email you when it moves.
Odds shift for weeks before departure. Track a flight and you'll hear when it moves up or down, when upgrade space opens, and the day before with where it stands.
Inventory tools tell you a seat is open. We tell you whether you'll get it.
ExpertFlyer and 2LNR watch inventory: they ping you when a seat shows up. That's useful — but an open seat isn't your seat. Between you and 2A sits the upgrade list, and that's the part we score.

Inventory alerts and odds answer different questions — plenty of people run both. If you already know a seat is open and just want to know whether it'll be yours, that's us.
