--- title: "Upgrade alerts: hear when a check finds space" description: "Get an alert when a check finds upgrade space on American, Delta or Alaska, or award space on more than 20 airlines. Email, SMS, in-app or push, checked daily." canonical: "https://2lnr.com/lp/real-time-alerts" url: "https://2lnr.com/lp/real-time-alerts.md" date_modified: "2026-10-10T00:00:00Z" --- # Upgrade alerts: be ready when space opens Upgrade space opens and closes without warning, and without alerts the only way to catch it is re-checking by hand. 2LNR checks upgrade space on American, Delta and Alaska and award space on more than 20 airlines every day, and sends a notification the moment a check finds space. When one flight matters right now, Update data re-checks it on demand. 2LNR alerts fire when a check finds tracked upgrade or award space, delivered by email, SMS, in-app, and push. You pick the route, dates, and upgrade type; 2LNR checks them daily and notifies you the moment a check finds space. Alert rules are included with Pro, with no cap on how many you run.

The question is whether you catch the window. ### Manual monitoring - Check the airline app multiple times per day for each flight you care about - Space can open close to departure, right when you're busiest with pre-trip logistics - No way to know if availability changed five minutes after your last check - Once you're watching more than two or three flights, keeping up by hand isn't sustainable - Miss a window and wait another day, or the rest of the booking period, for space to reappear ### 2LNR alerts - Define the route, date range, cabin class, and upgrade type you want to monitor - Receive an email, SMS, in-app, or push notification the moment a check finds matching inventory - Alerts fire on segment-level changes, not aggregated itinerary guesses - Watch dozens of flights at once, with no manual checking - Hear about an opening as soon as a check finds it, not days later when you happen to look ## Alerts built for upgrade hunters Granular controls so you get signal, not noise. ### Custom alert rules Set alerts by specific route pair, date range, cabin, and upgrade type. Want to know when upgrade space opens on DFW-LHR between March 10-15? One alert covers all flights in that window. ### Every channel Email, SMS, in-app, and push: enable any mix. Each notification names the flight, segment, cabin, and current seat count, so you can act without opening the app first. ### Segment-level triggers Alerts fire when a specific segment changes, not when a vague itinerary-level estimate shifts. If JFK-LHR opens upgrade space but DFW-JFK doesn't, you see exactly which leg changed. ### Schedule watches Retimes, equipment swaps, and cancellations ride the same alert engine. Keep tabs on your booked flight's schedule in the same place and the same inbox. ### Multi-flight monitoring Track availability across dozens of flights with independent alerts. Handy if you can shift dates by a day or two to catch confirmed space. ### Pause and resume Traveling and don't want notifications? Pause an alert without deleting it. Resume monitoring with a single tap when you're ready to act again. ## Who uses upgrade alerts ### Executive Platinum, Diamond Medallion & Atmos Platinum holders You're holding systemwide upgrades, Global or Regional Upgrade Certificates, or Alaska certs. Set alerts on your upcoming flights so you hear when a check finds upgrade space, then confirm your certificate before the seats fill. ### Business travelers who need flight-status alerts Flight status updates and alerts matter most when the trip is already booked and the day is already full. Tracked flights carry schedule-change notifications when a retime, equipment swap or cancellation lands, delay notices with the reason the airline filed, seat monitoring on the seat you actually chose, and a post-landing rebooking read on your onward connection. One inbox, per segment, without watching a departures board. ### Points & miles strategists You're watching upgrade availability to decide whether to buy a fare and upgrade or book an award ticket instead. Alerts let you wait for the right moment without obsessively checking. ## Frequently asked questions **What types of upgrade changes trigger an alert?** An alert fires when space opens for the upgrade type and cabin you chose: a flight and date on your route that shows confirmable seats and hasn't been reported to you yet. A seat count that moves on a flight you've already heard about, or space that closes again, doesn't send another alert. **How quickly are alerts delivered after availability changes?** There is no fixed delivery window, and we would rather say so than promise one. 2LNR checks the routes and dates you track about once a day, and an alert goes out on the next evaluation pass after a check finds space on your route and date. Space can open and close between two daily checks, so an alert reports what a check found, not a live feed. When you want one specific flight confirmed at this exact moment, click Update data on it in the upgrade matrix; that re-checks the flight live. **Can I set alerts for routes I haven't booked yet?** Yes. Alerts are not tied to a specific booking or reservation. You can monitor any covered route (American, Delta, or Alaska) and date combination regardless of whether you have purchased a ticket. This is useful for finding confirmed space before you commit to buying. **How many alerts can I have active at once?** As many as you like on Pro: unlimited alert rules, with no per-route or per-rule budget, so watching thirty date ranges costs the same as watching three. Manage, pause, or delete them anytime from your alerts. Pro is $175 a year or $50 a quarter. The free plan does not include alert rules. It covers the next 14 days on every product, upgrade space on American, Delta and Alaska and award seats on more than 20 airlines alike, mailbox trip import and loyalty tracking, at $0 with no credit card. Full details on the [pricing page](https://2lnr.com/pricing.md). **Do alerts work for connecting itineraries or just nonstop flights?** Alerts operate at the segment level. For a connecting itinerary, you set individual alerts for each segment. This gives you precise control, so you might watch only the long-haul leg and not the short domestic connection. New to alerts?
