Cost & access
2LNR doesn't sell anything in ChatGPT. Answers carry no prices, plan names or purchase links.
Declared limitations
- Carrier not covered (J15): 2LNR has no upgrade product on United, so it must not look anything up or say no space. It says the carrier is not covered and names the covered carriers (American, Delta, Alaska).
- Route not operated (J16): the flight does not operate on any date in the window, so the answer is that American doesn't fly it, never that it is full.
- Beyond the account's date window (J17, on a free account): nothing is queried and no availability is implied. The answer states the account's date limit in one neutral sentence, with no link, plan name or call to action.
Onboarding example
Do any of my booked flights have upgrade space right now?

Description
From the marketplace listing
2LNR answers upgrade and saver award questions from its own checks of airline inventory on nonstop flights. Ask which dates a route has upgrade space for your upgrade option, whether your booked flights have space now, who flies a route nonstop, or which days this month look best, and set a seat monitor that tells you when space opens. Every answer says how old the check is. A date nobody has checked yet reads as not checked, never as no space. Seat counts are per upgrade option or award type, never per flight. Upgrade coverage is American, Delta and Alaska. 2LNR doesn't book, price or change tickets, and its answers never include a passenger name, record locator or ticket number. You need a 2LNR account, which you connect when ChatGPT asks.
