# Seat Blocker Agent
|
||||||
|
|
||||||
|
Block middle seats (B/E) on Ryanair/Wizzair flights by creating dummy bookings that hold seats without completing payment. This gives the user better aisle/window seat options when they check in.
|
||||||
|
|
||||||
|
## Workflow Overview
|
||||||
|
|
||||||
|
1. **Reconnaissance** — Navigate to seat selection for the target flight, parse the seat map
|
||||||
|
2. **Blocking** — Create dummy bookings (up to 6 passengers each) selecting middle seats
|
||||||
|
3. **Notify** — Report blocked seats and warn about ~15 minute window
|
||||||
|
4. **Cleanup** — Close all tabs on user confirmation, bookings auto-expire
|
||||||
|
|
||||||
|
## Input Parsing
|
||||||
|
|
||||||
|
The user provides either:
|
||||||
|
- **Flight number + date**: e.g. `FR 1926 2026-04-15`
|
||||||
|
- **Booking reference + airline**: e.g. `ABC123 ryanair`
|
||||||
|
|
||||||
|
Parse airline from flight prefix:
|
||||||
|
- `FR` = Ryanair
|
||||||
|
- `W6` or `W9` = Wizzair
|
||||||
|
|
||||||
|
If ambiguous, ask the user which airline.
|
||||||
|
|
||||||
|
## Anti-Bot Stealth
|
||||||
|
|
||||||
|
Before ANY navigation, patch the webdriver flag:
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
Object.defineProperty(navigator, 'webdriver', {get: () => false});
|
||||||
|
```
|
||||||
|
|
||||||
|
Use `browser_evaluate` to run this on every new page/tab. Add human-like delays (1-3 seconds) between actions using `browser_evaluate` with `await new Promise(r => setTimeout(r, ms))`.
|
||||||
|
|
||||||
|
## Phase 1: Seat Map Reconnaissance
|
||||||
|
|
||||||
|
1. Navigate to the airline website
|
||||||
|
2. Accept cookies (snapshot the page, find and click the accept button)
|
||||||
|
3. Start a one-way booking: 1 adult, target flight
|
||||||
|
4. Navigate through to the seat selection screen
|
||||||
|
5. Parse the seat map to identify available middle seats (columns B and E)
|
||||||
|
6. Count available middle seats, calculate: `required_bookings = ceil(count / 6)`
|
||||||
|
7. Close/abandon this reconnaissance session
|
||||||
|
|
||||||
|
### Seat Map Parsing (priority order)
|
||||||
|
|
||||||
|
1. **`browser_snapshot`** (primary) — Use the accessibility tree to find seat elements. Seats are typically buttons with labels like "Seat 1B" or similar. Look for enabled/available middle seat buttons.
|
||||||
|
|
||||||
|
2. **`browser_network_requests`** (fallback) — Intercept the seat map API response. Airlines often fetch seat availability as JSON. Look for requests containing seat data with availability status per seat.
|
||||||
|
|
||||||
|
3. **`browser_take_screenshot`** (last resort) — Take a screenshot and visually analyze the seat map layout. Identify available vs taken seats by color coding.
|
||||||
|
|
||||||
|
## Phase 2: Seat Blocking
|
||||||
|
|
||||||
|
For each required booking (sequentially):
|
||||||
|
|
||||||
|
1. Open a new tab via `browser_tabs`
|
||||||
|
2. Navigate to the airline booking page
|
||||||
|
3. Book a one-way flight with **6 adults** (or fewer for the last booking if remaining middle seats < 6)
|
||||||
|
4. Fill fake passenger details (see Fake Data Generation below)
|
||||||
|
5. Skip bags/extras
|
||||||
|
6. At seat selection: select the next batch of available middle seats (B/E columns), one per passenger
|
||||||
|
7. **STOP before payment** — do NOT proceed to payment. Keep the page open.
|
||||||
|
8. Track which seats are held in which tab
|
||||||
|
|
||||||
|
### Important: Notify Early
|
||||||
|
|
||||||
|
After the FIRST booking completes seat selection, immediately notify the user so they can start their check-in while you continue blocking additional seats.
|
||||||
|
|
||||||
|
## Phase 3: Notify User
|
||||||
|
|
||||||
|
Report to the user:
|
||||||
|
- List of all blocked seats (e.g. "3B, 5E, 8B, 8E, 12B, 15E")
|
||||||
|
- Number of tabs/bookings holding them
|
||||||
|
- Timestamp of when blocking started
|
||||||
|
- Warning: "You have approximately 15 minutes to complete your check-in before these bookings expire"
|
||||||
|
|
||||||
|
Wait for user confirmation before proceeding to cleanup.
|
||||||
|
|
||||||
|
## Phase 4: Cleanup
|
||||||
|
|
||||||
|
- Close all browser tabs
|
||||||
|
- Confirm to user that abandoned bookings will auto-release their seats
|
||||||

|
||||||
|
**URL**: `https://www.ryanair.com/gb/en`
|
||||||
|
|
||||||
|
### Booking Flow
|
||||||
|
1. Search: one-way, departure → arrival, date, 1 adult (recon) or 6 adults (blocking)
|
||||||
|
2. Select the target flight from results
|
||||||
|
3. Choose "Value" fare (cheapest that allows seat selection)
|
||||||
|
4. Fill passenger details
|
||||||
|
5. Skip bags (continue without bags)
|
||||||
|
6. Seat selection screen — this is where we parse/select seats
|
||||||
|
|
||||||
|
### Seat Layout
|
||||||
|
```
|
||||||
|
A B C | D E F
|
||||||
|
```
|
||||||
|
Middle seats = **B** and **E**
|
||||||
|
|
||||||
|
### Flight Confirmation
|
||||||
|
Use the availability API to confirm flight exists before starting:
|
||||||
|
```
|
||||||
|
GET /api/booking/v4/en-gb/availability?dateOut=YYYY-MM-DD&origin=XXX&destination=YYY&adt=1&teen=0&chd=0&inf=0&FlexDaysBeforeOut=0&FlexDaysOut=0&ToUs=AGREED
|
||||||
|
```
|
||||||
|
|
||||||
|
## Wizzair-Specific Flow
|
||||||
|
|
||||||
|
**URL**: `https://wizzair.com`
|
||||||
|
|
||||||
|
### API Version Discovery
|
||||||
|
Wizzair requires knowing the current API version:
|
||||||
|
```bash
|
||||||
|
curl -sL https://wizzair.com | grep -oP 'be\.wizzair\.com(?:\\u002F|/)(\d+\.\d+\.\d+)'
|
||||||
|
```
|
||||||
|
|
||||||
|
### Booking Flow
|
||||||
|
1. Search: one-way, departure → arrival, date, 1 adult (recon) or 6 adults (blocking)
|
||||||
|
2. Select the target flight
|
||||||
|
3. Choose "BASIC" fare
|
||||||
|
4. Fill passenger details
|
||||||
|
5. Seat selection screen
|
||||||
|
|
||||||
|
### Seat Layout
|
||||||
|
```
|
||||||
|
A B C | D E F
|
||||||
|
```
|
||||||
|
Middle seats = **B** and **E**
|
||||||
|
|
||||||
|
## Fake Data Generation
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
**Surnames**: Smith, Jones, Williams, Brown, Taylor, Davies, Wilson, Evans, Thomas, Johnson, Roberts, Walker, Wright, Robinson, Thompson, White, Hughes, Edwards, Green, Hall, Lewis, Harris, Clarke, Jackson, Wood, Turner, Hill, Scott, Cooper, Morris

|
||||||
|
```
|
||||||
|
{first}.{last}{random 2-digit number}@sharklasers.com
|
||||||
|
```
|
||||||
|
Example: `james.smith42@sharklasers.com`
|
||||||
|
|
||||||
|
### Phone
|
||||||
|
```
|
||||||
|
+447{9 random digits}

|
||||||
|
|
||||||
|
### Title
|
||||||
|
Alternate between Mr and Ms based on the first name gender (male names → Mr, female names → Ms).
|
||||||
|
|
||||||
|
## Session/Tab Management
|
||||||
|
|
||||||
|
- Use `browser_tabs` to list and manage tabs
|
||||||
|
- Use `browser_tabs select <index>` before interacting with each tab
|
||||||
|
- Maintain a tracking structure:
|
||||||
|
```
|
||||||
|
Tab 1: seats [3B, 5E, 8B, 8E, 12B, 15E]
|
||||||
|
Tab 2: seats [16B, 16E, 19B, 19E, 22B, 22E]
|
||||||
|
```
|
||||||
|
- Always verify which tab is active before performing actions
|
||||||
|
|
||||||
|
## Error Handling
|
||||||
|
|
||||||
|
| Error | Action |
|
||||||
|
|-------|--------|
|
||||||
|
| Cookie consent popup | Snapshot page, find and click accept/agree button |
|
||||||
|
| CAPTCHA | Take screenshot, show to user, ask them to solve manually via AskUserQuestion |
|
||||||
|
| Bot detection / blocked | Patch `navigator.webdriver`, add longer delays, retry |
|
||||||
|
| Session timeout | Report which seats were lost, continue with remaining bookings |
|
||||||
|
| Flight sold out | Report to user immediately |
|
||||||
|
| No middle seats available | Report success — all middle seats already taken |
|
||||||
|
| Seat selection fails | Try next available middle seat, skip if none left |
|
||||||
|
| Page load timeout | Retry once, then report and continue |
|
||||||
|
| Unexpected page state | Take screenshot, snapshot, try to recover or ask user |
|
||||||
|
|
||||||
|
## Flight Number Reference
|
||||||
|
|
||||||
|
Common Ryanair/Wizzair route patterns:
|
||||||
|
- Ryanair: `FR` prefix, e.g. FR 1926, FR 8394
|
||||||
|
- Wizzair: `W6` or `W9` prefix, e.g. W6 4305, W9 1234
|
||||||
|
|
||||||
|
The user must also provide origin and destination airports if not inferrable from the flight number. Ask if not provided.
|
||||||
|
|
||||||
|
## Capacity Notes
|
||||||
|
|
||||||
|
- Ryanair 737-800: ~33 rows × 2 middle seats = ~66 middle seats max
|
||||||
|
- Realistically 20-40 available middle seats on a typical flight
|
||||||
|
- Each dummy booking blocks up to 6 middle seats
|
||||||
|
- Typical requirement: 4-7 bookings to block all middle seats
|
||||||
|
- 15-minute window is tight — start notifying user after first booking completes
