Look at the inventory before you buy the ticket, and the certificate goes from a waitlist gamble to an instant confirmation. Yes, there's a free AA SWU search tool. 2LNR's free plan shows systemwide upgrade space, the inventory that decides whether an SWU confirms or waitlists, per flight and per date for departures in the next 14 days, with no credit card. Pro opens the same calendar across the full 331-day horizon and adds unlimited alerts. [Start free, no card](https://2lnr.com/login) [See pricing](https://2lnr.com/pricing.md) $0 Free plan, no credit card 14 days Rolling matrix window, free 331 days Full horizon on Pro 3 Upgrade programs in one matrix ## Checking upgrade space by hand versus reading a calendar The information is the same. What changes is how many flights you can consider before you run out of patience. ### One flight, one date, by hand - Every question costs a separate lookup: this route, this date, this flight - Comparing five departure days means five rounds of the same work - No memory between checks, so you can't tell whether space just opened or has been there all week - Nothing watches the flight after you close the tab - By the time the pattern is obvious, the fare you wanted has moved ### The 2LNR upgrade matrix - Flights down one axis, dates across the other, with upgrade seat counts in the cells - A whole window of departure days is one glance, not five lookups - American, Delta and Alaska upgrade programs read the same way in the same grid - Free covers the next 14 days with no credit card; Pro covers all 331 - On-demand refresh is free inside the 14-day window when you want a cell re-checked now ## Three steps to your first SWU search No card, no trial timer, no sales call. 1 ### Create a free account Use an email and a password, or your Google account. The 14-day matrix is live immediately. 2 ### Pick American and your route Choose the upgrade program you hold and the city pair you fly. The matrix fills with upgrade space per flight and date, with exact seat counts. 3 ### Book against open space Buy a flight that already shows open upgrade space, apply the certificate, and it confirms instead of waitlisting. If nothing is open, that's what alerts on Pro are for. ## What's actually free, stated plainly Free plans are usually vague on purpose. This one isn't, so you can decide in thirty seconds whether it covers you. ### Included on the free plan - American systemwide upgrade space, plus Delta Global and Regional Upgrade Certificate space and Alaska first-class certificate space, in one matrix - A rolling 14-day window of departures, refreshed continuously - On-demand refresh of a cell inside that window - The award matrix for the same 14 days, across more than 20 airlines - Automatic trip import from Gmail or Outlook, loyalty balances and elite status tracking - The interactive route map, which needs no account at all ### What needs Pro - The full 331-day horizon on both matrices, which is where most SWU decisions actually happen - Unlimited alert rules by email, SMS, in-app and push - Seat monitoring on flights you've booked, and Flightdeck flight status and seat maps - $175 a year or $50 a quarter, cancel whenever ## Free SWU search questions **Is there really a free way to search AA SWU space?** Yes, within a 14-day window. 2LNR's free plan shows systemwide upgrade space per flight and date for American departures in the next 14 days, with exact seat counts, plus Delta and Alaska upgrade space in the same matrix. No credit card is required. Searching further out, up to the full 331-day horizon, is included with Pro at $175 a year or $50 a quarter. **Why does C class matter for a systemwide upgrade?** Because that is the bucket the upgrade clears into on the large majority of AA routes. If C shows seats when you apply the certificate, the upgrade confirms immediately. If it shows zero, the certificate waitlists and you are in a queue American orders by status, upgrade type and Loyalty Points. Checking C first is the whole difference between planning an upgrade and hoping for one. Upgrades from Business to Flagship First on the few aircraft that still offer it clear into A class instead. **Do I need a credit card to start?** No. The free plan takes an account and nothing else, there is no trial timer counting down, and nothing converts to paid on its own. If the 14-day window turns out to be the thing limiting you, going Pro is a deliberate decision you make later. **Can I get an alert when SWU space opens?** Alert rules are included with Pro. On Pro you can run unlimited alerts across your routes and dates, delivered by email, SMS, in-app and push, and they fire when matching upgrade space appears rather than on a schedule. The free plan does not include alerts, so on free the workflow is to check the matrix. The [SWU search guide](https://2lnr.com/guides/swu-search.md#how-to) shows the three ways to set an alert up. **Does it cover Delta and Alaska too?** Yes, on the free plan as well. The same 14-day matrix tracks Delta Global and Regional Upgrade Certificate space and Alaska first-class certificate inventory alongside American's systemwide upgrade space, so one grid covers all three programs. We check upgrade inventory on American, Delta and Alaska specifically, not every airline. **Does open C-class space guarantee the upgrade?** If C is open at the moment you apply the certificate, the upgrade confirms and the seat is yours. Nothing about a search tool creates inventory, and if you are already waitlisted when space opens later, the airline's clearance priority decides who gets it. That is exactly the argument for booking against space that is already open.
