Upgrade tracking built for the people who actually upgrade
2LNR monitors confirmed upgrade availability on American Airlines at the segment level. It exists because the information you need to make upgrade decisions — which flights have C-class open right now, which routes consistently release inventory, when to use an SWU versus saving it — is scattered across multiple tools and takes too long to piece together manually.
If you hold Executive Platinum or Platinum Pro status, have SWUs to deploy, or fly enough to care about complimentary upgrade priority, this is the tool we built for you.
What 2LNR does
At its core, 2LNR answers one question: which flights have confirmed upgrade space right now? Everything else — alerts, route maps, trip planning — supports that central function.
Segment-level upgrade inventory
AA prices and releases upgrade space per segment, not per itinerary. A DFW-LHR-CDG trip has two separate upgrade decisions. 2LNR tracks each segment independently so you see the full picture before you commit an upgrade instrument.
We monitor C-class (business), Z-class (discounted business), and first-class availability on AA-operated flights across 200+ airports.
Real-time monitoring and alerts
Upgrade inventory changes constantly. Space that was sold out at noon can open at 2 PM when a revenue passenger rebooks. 2LNR monitors your routes continuously and sends alerts the moment confirmed space appears.
Alerts go out via push notification, email, or SMS — whichever gets to you fastest.
Route intelligence
Not all routes are equal for upgrades. Some consistently release C-class inventory; others rarely do. The route explorer shows you which routes have historically strong upgrade availability, helping you plan trips around routes where upgrades are realistic, not aspirational.
Loyalty program data
Transfer bonus tracking across Amex, Chase, Citi, and Capital One. Point valuation data for airline and hotel programs. The information you need to decide whether to transfer points now or wait for a bonus.
Who this is for
2LNR is not for everyone. It is specifically built for travelers who already understand how airline upgrades work and want better tools to execute their strategy.
Executive Platinum and Platinum Pro members
You have four SWUs per year (or eight if you re-qualified). Each one is worth thousands of dollars on the right route. 2LNR helps you deploy them on flights where C-class is confirmed, so you stop burning SWUs on waitlisted flights that never clear.
Points and miles strategists
You track transfer bonuses, know your cost-per-point targets, and time your transfers. 2LNR surfaces transfer bonus data and program valuations alongside upgrade availability so you can make informed decisions in one place.
Frequent flyers who want the data
You fly 75K+ miles per year and complimentary upgrades are part of your travel experience. You want to know which flights on your route have the best upgrade odds — not a vague promise, but actual inventory data.
What makes 2LNR different
There are other tools that show flight availability. Here is what 2LNR does differently.
Upgrade-first design
Most flight search tools are built for booking revenue tickets or finding award space. Upgrade availability is an afterthought, buried in a sub-menu or requiring a separate search. 2LNR starts with upgrades. The entire interface — calendar views, filters, alerts — is designed around the upgrade decision: is confirmed space available on this flight, for this upgrade type, on this date?
Segment-level accuracy
Connecting itineraries are the norm for AA's hub-and-spoke network. A DFW-LHR flight might route through CLT or PHL. Each segment has independent upgrade inventory. 2LNR shows availability at the segment level so you know exactly where the upgrade will and will not clear, rather than getting a single misleading "available" or "unavailable" for the whole trip.
Continuous monitoring
Checking aa.com once and seeing "no availability" tells you nothing about what happens in the next 60 days. Upgrade inventory fluctuates as passengers change bookings, revenue management adjusts allocations, and departure day approaches. 2LNR monitors routes continuously so you catch the window when it opens.
Built for people who already know what they are doing
2LNR does not explain what an SWU is in every tooltip. It does not pad the interface with onboarding tutorials about fare classes. It assumes you know C-class from R-class and gives you the data without condescension. If you need the background, our airline guides have it, but the tool itself is designed for practitioners.
