SAS bonus watch userscript
Tampermonkey/Violentmonkey userscript that watches SAS EuroBonus award availability from a sas.se tab and notifies via ntfy, Discord, Slack, webhook or desktop when matching seats appear. Moved here from sas-bonus-finder; update URLs point at this public repo. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# SAS bonus watch
|
||||||
|
|
||||||
|
A Tampermonkey / Violentmonkey userscript that watches SAS EuroBonus award availability and notifies you when
|
||||||
|
seats you care about appear. It runs inside your own browser, so requests to sas.se are ordinary same-origin
|
||||||
|
browser requests and it keeps working behind sas.se's Cloudflare protection.
|
||||||
|
|
||||||
|
- Any number of **watches**: origins, destinations, one travel window, cabins (Go / Plus / Business), seats, max stops
|
||||||
|
- Finds **outbound and return** flights inside the window; optionally only alerts when both legs exist, with min/max nights
|
||||||
|
- **Gentle on sas.se**: about one request a minute, a full sweep at most every 15 minutes, backs off when refused
|
||||||
|
- Alerts via **ntfy** (phone push), **Discord**, **Slack**, any **webhook**, and desktop notifications
|
||||||
|
- Dashboard shows what is bookable now **and what you missed**: seat drops and sold-out flights
|
||||||
|
|
||||||
|
## Install
|
||||||
|
|
||||||
|
1. Install [Tampermonkey](https://www.tampermonkey.net/) (Firefox, Chrome, Edge, Safari) or
|
||||||
|
[Violentmonkey](https://violentmonkey.github.io/).
|
||||||
|
2. Open the raw script and let the extension install it:
|
||||||
|
**<https://gitea.mscloud.site/mans/sas-bonus-watch/raw/branch/main/sas-bonus-watch.user.js>**
|
||||||
|
(or: Tampermonkey → *Create a new script* → paste the file → save).
|
||||||
|
3. Open **<https://www.sas.se/robots.txt>** and keep that tab open. It turns into the dashboard.
|
||||||
|
Pin the tab so the browser doesn't unload it.
|
||||||
|
|
||||||
|
> **Chrome / Edge:** userscripts need *Developer mode* enabled on `chrome://extensions` (or "Allow user scripts"
|
||||||
|
> in the Tampermonkey extension details) since Manifest V3.
|
||||||
|
|
||||||
|
## Set up
|
||||||
|
|
||||||
|
In the **Config** section of the dashboard:
|
||||||
|
|
||||||
|
1. **Watches** – one row per search:
|
||||||
|
|
||||||
|
| Column | Meaning |
|
||||||
|
|---|---|
|
||||||
|
| On | Pause a watch without deleting it |
|
||||||
|
| From / To | Airport codes, comma-separated (`ARN, CPH`). Every From × To pair is checked |
|
||||||
|
| Earliest / Latest | Travel window. Outbound **and** return flights departing in it are found |
|
||||||
|
| Cabins | Go (AG), Plus (AP), Business (AB) |
|
||||||
|
| Seats | Seats needed **on the same flight** |
|
||||||
|
| Stops | Any, direct only, or at most 1 / 2 stops |
|
||||||
|
| Both legs | Only alert when an outbound has a later return in the window (default on). Off = alert for either direction on its own |
|
||||||
|
| Nights | Optional min / max stay, measured between the two departure dates (turns on Both legs) |
|
||||||
|
|
||||||
|
2. **Notifications** – add one or more targets:
|
||||||
|
|
||||||
|
| Type | URL |
|
||||||
|
|---|---|
|
||||||
|
| `ntfy` | `https://ntfy.sh/<long-random-topic>`. Install the ntfy app and subscribe to the same topic. Priority sets how loud it is |
|
||||||
|
| `discord` | A channel webhook URL |
|
||||||
|
| `slack` | An incoming-webhook URL |
|
||||||
|
| `webhook` | Anything; receives `POST` JSON `{title, body, watch, matches: [...]}` |
|
||||||
|
|
||||||
|
The first time the script posts to a host, Tampermonkey asks you to allow it — choose *Always allow domain*.
|
||||||
|
|
||||||
|
3. Press **Save & restart**, then **Test notification**.
|
||||||
|
4. Optional: **Baseline (no alerts)** records what is available right now, so you are only told about new seats.
|
||||||
|
|
||||||
|
### JSON export / import / reset
|
||||||
|
|
||||||
|
Under the tables, **JSON – export / import / reset** holds the same config as JSON:
|
||||||
|
*Download .json* for a backup, *Load file…* or paste + *Apply JSON to tables* to restore,
|
||||||
|
*Reset to example* to start over. Nothing takes effect until you press **Save & restart**.
|
||||||
|
|
||||||
|
## Dashboard
|
||||||
|
|
||||||
|
- **Current matches** per watch:
|
||||||
|
- `Go ×8 −2` – bookable now; the red number is how many seats were taken since the highest count seen
|
||||||
|
- red, struck through, *gone 12 okt 13:42* – sold out (or below your seat count); kept for two weeks or until departure
|
||||||
|
- grey, *no matching return* – still has seats, but its return disappeared (with Both legs)
|
||||||
|
- **Recent changes**: `+` new / back, `▲` more seats, `▼` fewer seats, `−` gone, `○` lost its return
|
||||||
|
- **Log**: every request and sweep
|
||||||
|
|
||||||
|
You are notified only when seats are **new or come back**. Drops and sold-out flights are shown, not pushed.
|
||||||
|
|
||||||
|
## How it polls
|
||||||
|
|
||||||
|
1. **Calendar** – `/bff/award-finder/destinations/v1?origin=ARN&destinations=HND&passengers=N`: one request per
|
||||||
|
route pair returns every date with seats **in both directions**. With `passengers=N` it only counts flights
|
||||||
|
that have N free seats.
|
||||||
|
2. **Details** – `/bff/award-finder/routes/v1?origin=…&destination=…&departureDate=…`: only for dates in your
|
||||||
|
window that have seats in your cabins, and only when that date's calendar entry changed (or every 6 h).
|
||||||
|
|
||||||
|
Requests are at least 40 s apart (+0–20 s random) and a sweep starts at most every 15 minutes; both are adjustable
|
||||||
|
under *Request pacing* (minimum 20 s). If sas.se refuses requests, the script backs off exponentially (up to an hour),
|
||||||
|
the badge turns red (*blocked – reload this tab*) and you get a notification. Reload the tab and complete the check
|
||||||
|
if sas.se shows one.
|
||||||
|
|
||||||
|
Only one tab polls at a time, so opening the dashboard twice does not double the rate.
|
||||||
|
|
||||||
|
## Limitations
|
||||||
|
|
||||||
|
- Runs only while the browser is open and the computer awake.
|
||||||
|
- Firefox / Chrome may unload background tabs under memory pressure; pinning the tab usually prevents it.
|
||||||
|
- Config, matches and history live in the userscript manager's storage on that browser only. Use *Download .json*
|
||||||
|
to move the config elsewhere.
|
||||||
|
|
||||||
|
## Auto-update
|
||||||
|
|
||||||
|
The script header points Tampermonkey at this repo:
|
||||||
|
|
||||||
|
```
|
||||||
|
// @version 1.1.1
|
||||||
|
// @updateURL https://gitea.mscloud.site/mans/sas-bonus-watch/raw/branch/main/sas-bonus-watch.user.js
|
||||||
|
// @downloadURL https://gitea.mscloud.site/mans/sas-bonus-watch/raw/branch/main/sas-bonus-watch.user.js
|
||||||
|
```
|
||||||
|
|
||||||
|
Tampermonkey periodically downloads `@updateURL` (default once a day; *Dashboard → Settings → Script Update*, or
|
||||||
|
*Check for userscript updates* in the extension menu to force it) and installs the new file **only if its
|
||||||
|
`@version` is higher**. Settings and history are kept across updates.
|
||||||
|
|
||||||
|
Requirements:
|
||||||
|
|
||||||
|
- **The raw URL must be readable without logging in.** Tampermonkey cannot send Gitea credentials, so the repo
|
||||||
|
(or at least this file) must be public. Check by opening the raw URL in a private window.
|
||||||
|
If the repo has to stay private, publish just the `.user.js` somewhere public (a public mirror repo, or a public
|
||||||
|
Gitea release asset) and point both URLs there.
|
||||||
|
- The script must be installed from that URL (or have the header above) for updates to be picked up.
|
||||||
|
- `@name` and `@namespace` must never change, or Tampermonkey treats it as a different script and the new copy
|
||||||
|
starts with an empty config.
|
||||||
|
|
||||||
|
### Releasing a change
|
||||||
|
|
||||||
|
1. Edit `sas-bonus-watch.user.js`.
|
||||||
|
2. Run the tests: `node --test` (Node 20+).
|
||||||
|
3. **Bump `@version`** (e.g. 1.1.1 → 1.1.2). Without this, nobody gets the update.
|
||||||
|
4. Commit and push to `main`.
|
||||||
|
|
||||||
|
## Development
|
||||||
|
|
||||||
|
- `sas-bonus-watch.user.js` – the script. The pure logic (config validation, parsing, matching, state diffing)
|
||||||
|
is exported to Node when loaded with `require`, the browser part only runs in the userscript manager.
|
||||||
|
- `sas-bonus-watch.test.cjs` – tests for the logic using response shapes captured from sas.se. Run `node --test`.
|
||||||
|
|
||||||
|
Nothing is sent anywhere except sas.se and the notification targets you configure.
