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 can provide input in any of these forms (from most to least specific):

1. Flight number + date: e.g. FR 1926 2026-04-15
2. Booking reference + airline: e.g. ABC123 ryanair
3. Rough description: e.g. Stansted to Sofia, 21st March, 16:55 or London to Malaga tomorrow evening

For forms 1 and 2, parse airline from flight prefix:

• FR = Ryanair
• W6 or W9 = Wizzair

For form 3 (rough description), proceed to Phase 0: Flight Search to resolve the exact flight.

Airport Name Resolution

Map common city/airport names to IATA codes. Handle misspellings with fuzzy matching:

• "Stansted" / "Stanstead" → STN
• "Luton" → LTN
• "Gatwick" → LGW
• "Sofia" → SOF
• "Malaga" / "Málaga" → AGP
• "Barcelona" / "Barca" → BCN
• "Budapest" → BUD
• "Bucharest" → OTP
• "Faro" → FAO
• "Athens" → ATH
• "Naples" / "Napoli" → NAP
• "Rome" / "Roma" → FCO/CIA
• "Milan" / "Milano" → MXP/BGY
• "Palma" / "Mallorca" / "Majorca" → PMI
• "Lisbon" / "Lisboa" → LIS

For "London" without a specific airport, search ALL London airports (STN, LTN, LGW) across both airlines.

If a city name can't be resolved, ask the user for the IATA code.

Phase 0: Flight Search

When the user provides a rough description instead of an exact flight number, use the airline APIs to find matching flights and ask for confirmation.

Step 1: Determine Airlines to Search

• If origin/destination is known to be Ryanair-only or Wizzair-only, search just that airline
• Otherwise, search BOTH airlines in parallel (Ryanair first, then Wizzair)

Step 2: Query Ryanair Availability API

curl -s "https://www.ryanair.com/api/booking/v4/en-gb/availability?ADT=1&CHD=0&INF=0&TEEN=0&DateOut=YYYY-MM-DD&Origin=XXX&Destination=YYY&FlexDaysOut=0&FlexDaysIn=0&RoundTrip=false&ToUs=AGREED" \
  -H "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36"

Response contains trips[].dates[].flights[] with:

• flightNumber: e.g. "FR 1926"
• time: ["2026-04-15T16:55:00.000", "2026-04-15T20:25:00.000"] (departure, arrival)
• duration: e.g. "03:30"
• faresLeft: seats remaining (-1 = plenty)
• regularFare.fares[].amount: price per person

Step 3: Query Wizzair Timetable API

First discover the API version:

WIZZ_VERSION=$(curl -sL https://wizzair.com | grep -oP 'be\.wizzair\.com(?:\\u002F|/)(\d+\.\d+\.\d+)' | head -1 | grep -oP '\d+\.\d+\.\d+')

Then search flights:

curl -s -X POST "https://be.wizzair.com/${WIZZ_VERSION}/Api/search/search" \
  -H "Content-Type: application/json" \
  -H "Origin: https://wizzair.com" \
  -H "Referer: https://wizzair.com/" \
  -d '{"flightList":[{"departureStation":"LTN","arrivalStation":"SOF","departureDate":"2026-04-15"}],"adultCount":1,"childCount":0,"infantCount":0}'

Fallback to fare chart API if search endpoint is restricted:

curl -s -X POST "https://be.wizzair.com/${WIZZ_VERSION}/Api/asset/farechart" \
  -H "Content-Type: application/json" \
  -H "Origin: https://wizzair.com" \
  -H "Referer: https://wizzair.com/" \
  -d '{"adultCount":1,"childCount":0,"infantCount":0,"dayInterval":1,"wdc":false,"isRescueFare":false,"flightList":[{"departureStation":"LTN","arrivalStation":"SOF","date":"2026-04-15"}]}'

Note: Wizzair prices are Discount Club prices — add £9.20/leg for non-member pricing.

Step 4: Match User's Description

If the user specified a time (e.g. "16:55"), find the flight closest to that time. If multiple flights exist on that date, rank by time proximity.

If the user said "evening", filter to flights departing 17:00-23:59. "Morning" = 05:00-11:59. "Afternoon" = 12:00-16:59.

Step 5: Confirm with User

Present the matched flight(s) to the user and ask for confirmation:

Found matching flight:
  FR 1926 | STN → SOF | 21 Mar 2026
  Departs: 16:55 → Arrives: 22:25 (3h 30m)
  Price: £45/person | Seats left: plenty

Is this the correct flight? (yes/no)

If multiple close matches exist, present up to 3 options and ask the user to pick one.

Only proceed to Phase 1 after user confirms the flight.

Anti-Bot Stealth

Before ANY navigation, patch the webdriver flag:

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

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
