How upgrade and award alerts work

2LNR alerts watch upgrade and award availability on the routes, dates, and cabins you choose, and notify you the moment a check finds space. Upgrade and award inventory changes between checks, so a person checking an airline app only sees the moments they look. Alerts run in the background on a daily check, so you never have to remember to look, and reach you by email, SMS, in-app, or push, whichever channels you turn on.

A 2LNR alert is a standing watch on a route, date range, and cabin. The engine checks upgrade and award availability daily and notifies you by email, SMS, in-app, or push the moment a check finds space. Premium inventory changes between checks, so a standing watch catches what a manual check would miss.

Key insight: Upgrade and award space changes between checks, so a manual check only sees the moment you look. 2LNR does the checking for you every day and tells you the moment a check finds space on a tracked segment.

How it works

Four steps, and only the first one takes any effort on your part. Once an alert is set, the monitoring and the notification happen on 2LNR's side.

1

Define what to watch

Pick a route (one city pair, or several origins and destinations at once), a date range, the cabin or upgrade type you want, and the airline. One alert can cover a full month of flights on that route, not just a single date.

2

2LNR checks every day

Once the alert is set, 2LNR checks upgrade and award inventory on your routes daily, down to the individual flight segment. You don't have to refresh anything or check back yourself.

3

Get notified the moment a check finds space

When matching availability opens on a tracked segment, the alert fires through whichever channels you enabled: email, SMS, in-app, or push. You can turn on more than one channel for the same alert.

4

Act while the window is open

Upgrade and award space can close again. The notification tells you what changed and on which flight, so you can book, apply a certificate, or redeem miles before the space disappears.

What you can track

Alerts cover more than upgrade and award seats. Each of these fires the same way: a change on a tracked flight reaches you through the channels you turned on.

Upgrade space by route and cabin

Confirmed upgrade availability by cabin, matched to the route and date range you set, on American, Delta, and Alaska.

Award seats on more than 20 airlines

Award inventory across more than 20 airlines, tracked the same way as the upgrade product.

Seat-quality changes

A notification when a better seat than your current assignment opens up on a flight you're tracking.

Seat loss or reassignment

A notification if your booked seat is moved or taken away.

Aircraft swaps

A notification when the airline changes the aircraft on a tracked flight.

Schedule changes

A notification when a tracked flight is retimed.

Award availability alerts

An award rule watches the award bucket 2LNR reads for that carrier, on the routes and dates you pick, across more than 20 airlines. When a seat opens in that bucket we tell you through the channels you turned on, by email, SMS, in-app or push, the same way an upgrade rule works. Alerts are included with Pro. How we read award space is covered in how to check award availability.

Frequently asked questions

What is an upgrade alert?
An upgrade alert is a standing watch on a route, date range and cabin. 2LNR keeps checking, and when space opens it tells you by email, SMS, in-app or push. Alerts are included with Pro.
What notification channels can I use for alerts?
Email, SMS, in-app, and push. You can turn on more than one channel for the same alert, so a change reaches you wherever you're most likely to see it first.
What is a flight segment?
A flight segment is one takeoff and one landing under a single flight number: the leg from one airport to the next. A nonstop JFK to LAX booking is one segment. A JFK to DFW to LAX connection is two segments, even though it is one ticket and one itinerary. Airlines count segments, not tickets, which is why a two-connection trip reads as three flight segments on your statement, and why availability has to be evaluated leg by leg. A segment is also distinct from a leg in the strict sense: a through-flight that keeps the same number across an intermediate stop is filed as one segment with two legs.
Do alerts track individual flight segments or the whole itinerary?
Individual segments. If your trip has a connection, each leg is evaluated on its own, so a change on one segment is never lost inside an averaged view of the full itinerary. That matters because upgrade and award space is filed per segment: the JFK to DFW leg can open while DFW to LAX stays closed, and a whole-itinerary view would show you neither.
How fast do alerts fire after availability changes?
2LNR runs its checks in the background about once a day, so a notification goes out once a check finds the change on a tracked segment. You don't need the app open or need to be checking anything yourself.
Can I track more than one route at a time?
Yes. You can set alerts on as many routes as you want, each with its own date range, cabin, and airline. Tracking five routes takes the same effort on your end as tracking one, since the checking happens on 2LNR's side.
Does it cost anything to start?
No. Creating a 2LNR account and browsing upgrade and award availability is free. Alerts are a Pro-tier feature, so turning on notification rules requires a Pro subscription.
How is this different from checking the airline's app myself?
Checking the app yourself only tells you what's available at the exact moment you look. Upgrade and award space changes between checks, so a few days without looking can mean missing an opening. 2LNR checks every day and tells you the moment a check finds space, without you having to remember to look.
