Built by people who check upgrade availability before booking the ticket
2LNR exists because the people who built it are the same people who use it. We are frequent flyers, upgrade strategists, and unrepentant aviation geeks who got tired of manually checking aa.com four times a day to see if C7 space opened on our DFW-NRT routing.
So we built the tool we wished existed.
What's an AvGeek?
Short for aviation geek. It is a term of endearment in the frequent flyer community for people whose interest in air travel goes well beyond getting from A to B.
The spotter
Knows the difference between a 777-200ER and a 777-300ER by the engine nacelles. Has opinions about winglets. Tracks tail numbers for fun.
The strategist
Knows exactly how many miles to requalify, which routes release upgrade space on Tuesdays, and the optimal time to apply an SWU. Has a spreadsheet for everything.
The route nerd
Gets excited about new route announcements. Knows which hubs have the best connections. Has booked positioning flights just to try a specific aircraft type.
We are all three. And the product reflects it.
Why we built this
We had the same problem you do. Upgrade availability data is scattered, stale, and painful to check manually. We wanted a single place that answers the question: where is confirmed upgrade space open right now?
Scratching our own itch
2LNR started as a personal project. A spreadsheet that scraped availability data for our own trips. Then friends wanted access. Then their friends. At some point the spreadsheet needed to become a product, so we built one — with the same obsessive attention to detail we bring to planning our own itineraries.
Built for practitioners, not tourists
We do not explain what a fare class is in every tooltip. We do not pad the interface with beginner tutorials. If you know the difference between C and Z availability, you are our people. 2LNR is designed for travelers who already understand upgrades and want better tools — not a gentler learning curve.
Passion project, production grade
The enthusiasm is genuine. The engineering is serious. We monitor thousands of routes in real time, process millions of data points, and deliver alerts within minutes of availability changes. Because when C7 opens on your LAX-HND flight, you need to know now — not tomorrow.
The details we obsess over
When AvGeeks build a product, the details matter. Here is some of the aviation nerdery baked into 2LNR.
Segment-level tracking
Because we know that a DFW-LHR-CDG itinerary has two independent upgrade decisions. Showing a single "available" or "unavailable" for a connecting trip is misleading. We track each segment independently because that is how upgrades actually work.
Route intelligence
Some routes consistently release upgrade inventory. Others almost never do. We surface historical availability patterns so you can plan trips around routes where upgrades are realistic, not routes where you will sit in economy wondering what went wrong.
Saver fare detection
Not all award availability is equal. We distinguish saver-level fares from standard pricing using distance-based thresholds, because an AvGeek knows the difference between 60K miles and 200K miles for the same seat matters.
Real-time alerts
Upgrade inventory changes constantly. Revenue passengers rebook, RM adjusts allocations, and space opens at 2 PM that was sold out at noon. We built alerts that reach you via push, email, or SMS within minutes — because in upgrade availability, timing is everything.
