EXTRACTION RULES - FOLLOW THESE STEPS EXACTLY:

STEP 1 - FLIGHT INFO EXTRACTION:
- operator: Extract from "OPERATOR:", "ACFT OPERATOR", or clear company names
- aircraft_type: Extract from "AIRCRAFT:", "ACFT TYPE:", "TYPE:" (LJ45, Boeing 737, etc.)
- registry: Extract from "REG. NBR:", "REGISTRATION:", "ACFT REGISTRY:" (DS-87TH, etc.)
- callsign: Extract from schedule lines or "CALLSIGN:" field
- operation_date: Use first flight date from schedule, convert to YYYY-MM-DD
- If any field is missing, use null

STEP 2 - FLIGHT ROUTES EXTRACTION (ENHANCED FOR COMPLEX SCHEDULES):
- Parse ALL schedule lines containing airport codes and times
- Handle various formats:
  * "CALLSIGN ORIGIN TIME -- DESTINATION TIME DATE"
  * "DATE CALLSIGN ORIGIN ETD/TIME ETA/TIME DESTINATION" 
  * Mixed formats with different separators
- Extract origin and destination airports (never leave as N/A)
- Convert all dates to YYYY-MM-DD format
- Convert all times to HH:MM format (remove Z suffix)
- Handle formats: "15AUG", "15-AUG", "15 AUG 2025", "17-SEP", "21/22-SEP" → proper YYYY-MM-DD
- CRITICAL: Always populate origin and destination fields with actual airport codes

STEP 3 - PERMITS EXTRACTION (EXPLICIT ONLY):

3A. Extract ONLY Explicit Permits (ENHANCED FOR COMPLEX MULTI-SEGMENT PARSING):
- Search ENTIRE email text for permit-related sections, including:
  * "REQUIRED Permits:" sections followed by route-specific listings
  * Route-specific format: "ORIGIN - DESTINATION (DATE): COUNTRY1, COUNTRY2 OVF PERMITS"
  * "OVF PERMIT FOR BOTH SECTORS" 
  * Country names followed by "OVF PERMITS" or "LND PERMIT"
  * Bullet points listing countries with permit types
  * Multi-line permit specifications with route breakdowns

- Parse route-specific permit requirements:
  * Extract date from route segment (e.g., "17-SEP'2025")
  * Extract countries from that segment (e.g., "NIGER, BURKINA FASO, ALGERIA")
  * Associate each country+permit type with the specific date
  
- Handle landing permits mentioned separately:
  * "DNAA LND PERMIT" = Nigeria Landing permit
  * "FZAA LND PERMITS" = DRC Landing permit
  
- Map airport codes to countries: FTTJ=Chad, HSSS=Sudan, HECA=Egypt, OEJN=Saudi Arabia, OBBB=Bahrain, OMAA=UAE, SBGR=Brazil, DAAG=Algeria, DNAA=Nigeria, EGSS=UK, DNKN=Nigeria, FZAA=DRC, LMML=Malta, LFPB=France, LEMD=Spain, FOOL=Liberia, FCBB=Gabon, GMMN=Morocco, GMMX=Morocco, DFFD=Nigeria

- CRITICAL: Never return empty permits if "REQUIRED Permits:" section exists

3B. Date-Aware Consolidation (CRITICAL LOGIC - ROUTE-SEGMENT CONSOLIDATION):
- After extracting all permits from route segments, consolidate by country+permit type:
- For each unique country+permit combination:
  * Collect ALL dates where that country+permit is mentioned across ALL route segments
  * Set quantity = TOTAL count of unique dates for that country+permit
  * Include ALL relevant dates in "dates" array
  
- CRITICAL EXAMPLES from complex route-segment parsing:
  * Niger OVF appears in: 17-SEP, 19-SEP, 20-SEP, 21-SEP, 22-SEP segments
    Result: Niger OVF quantity=5, dates=["2025-09-17", "2025-09-19", "2025-09-20", "2025-09-21", "2025-09-22"]
    
  * Chad OVF appears in: 21-SEP, 22-SEP segments only  
    Result: Chad OVF quantity=2, dates=["2025-09-21", "2025-09-22"]
    
  * Gabon OVF appears in: 22-SEP segment only
    Result: Gabon OVF quantity=1, dates=["2025-09-22"]
    
  * DNAA Landing permit mentioned separately
    Result: Nigeria Landing quantity=1, dates=["2025-09-19"] (from route context)

3C. If No Permits Mentioned:
- Return empty permits array: []

STEP 4 - HANDLING SERVICES EXTRACTION:

4A. Identify ALL Landing Airports (Destinations + Intermediate Stops):
- From flight_routes, extract ALL airports where aircraft lands (not just final destinations)
- Include: Final destination of each route segment + any intermediate stops mentioned
- Exclude: Only the very first origin airport of the entire journey
- Example Route: "FZAA→OMDB→HJKJ" = Landing airports: OMDB (intermediate), HJKJ (final)
- Example Multi-leg: "DAAG→OMAA" + "OMAA→SBGR" = Landing airports: OMAA, SBGR

4B. Auto-Add Mandatory Services for ALL Landing Airports:
- For EVERY landing airport identified in step 4A, automatically add:
  1. "Ground-Handling" at that location
  2. "Airport-Fees" at that location

4C. Add Explicit Services (ENHANCED FOR LOCATION-SPECIFIC REQUESTS):
- Search for location-specific handling requests in formats like:
  * "DNAA LND PERMIT GROUND HANDLING CREW HOTAC TRANSPORTATION CATERING"
  * "FZAA LND PERMITS GROUND HANDLING CREW HOTAC TRANSPORTATION VIP LOUNGE CATERING"
  * "OMAA GROUND HANDLING SERVICES, VIP LOUNGE"
  
- Parse handling services mentioned after airport codes:
  * Extract airport code (DNAA, FZAA, OMAA, etc.)
  * Extract services mentioned for that specific location
  * Map services: HOTAC="Hotac", "VIP LOUNGE"="VIP-Lounge", etc.
  
- For each mentioned location, add explicitly requested services:
  * "VIP-Lounge" (for VIP, LOUNGE keywords)
  * "Hotac" (for HOTAC, HOTEL keywords)  
  * "Transportation" (for TRANSPORT, TRANSFER keywords)
  * "Catering" (for CATERING, MEAL keywords)
  
- IMPORTANT: Do NOT duplicate Ground-Handling/Airport-Fees if already added in step 4B
- Handle both general handling requests and location-specific requests

4D. If No Landing Airports Found:
- Return empty handling_services array: []

DEFAULT VALUES:
- quantity: Set based on date consolidation logic
- status: "PENDING"
- payment_mention: "Credit" 
- dates: Array of all relevant dates

CRITICAL EXAMPLES FOR VALIDATION:

Example 1 - Explicit Permits Only:
Input: "VRS010 LSZH→FTTJ on 19-AUG, request FTTJ LND PERMIT"
MUST Generate:
- Chad Landing (explicitly requested): quantity=1, dates=["2025-08-19"]
- NO other permits (destinations don't auto-generate permits)

Example 2 - Complex Multi-Date Permits (CRITICAL TEST CASE):
Input: "Niger OVF required for flights on 17-SEP, 19-SEP, 20-SEP, 21-SEP, 22-SEP"
MUST Generate:
- Niger OVF: quantity=5, dates=["2025-09-17", "2025-09-19", "2025-09-20", "2025-09-21", "2025-09-22"]

Example 4 - Complex Route-Segment Permits (THE FAILING TEST CASE):
Input: 
"REQUIRED Permits:
DNMM – LMML (17-SEP'2025): NIGER, BURKINA FASO, ALGERIA OVF PERMITS
LMML – DNAA (19-SEP'2025): NIGER, BURKINA FASO, ALGERIA OVF PERMITS / DNAA LND PERMIT  
LEMD – FZAA (21/22-SEP'2025): NIGER, BURKINA FASO, ALGERIA, CHAD, CAMEROON OVF PERMITS, FZAA LND PERMIT
FZAA – DAAG (22-SEP'2025): NIGER, BURKINA FASO, ALGERIA, CHAD, CAMEROON, GABON OVF PERMITS"

MUST Generate:
- Niger OVF: quantity=5, dates=["2025-09-17", "2025-09-19", "2025-09-20", "2025-09-21", "2025-09-22"]
- Burkina Faso OVF: quantity=5, dates=["2025-09-17", "2025-09-19", "2025-09-20", "2025-09-21", "2025-09-22"] 
- Algeria OVF: quantity=5, dates=["2025-09-17", "2025-09-19", "2025-09-20", "2025-09-21", "2025-09-22"]
- Chad OVF: quantity=2, dates=["2025-09-21", "2025-09-22"]
- Cameroon OVF: quantity=2, dates=["2025-09-21", "2025-09-22"] 
- Gabon OVF: quantity=1, dates=["2025-09-22"]
- Nigeria Landing: quantity=1, dates=["2025-09-19"]
- DRC Landing: quantity=1, dates=["2025-09-21"]

Example 5 - Location-Specific Handling:
Input: "DNAA GROUND HANDLING CREW HOTAC TRANSPORTATION CATERING, FZAA VIP LOUNGE CATERING"
MUST Generate:
- DNAA: Ground-Handling, Airport-Fees, Hotac, Transportation, Catering
- FZAA: Ground-Handling, Airport-Fees, VIP-Lounge, Catering

Example 3 - All Landing Airports Get Handling:
Input: "Flight FZAA→OMDB→HJKJ (15-Jul-2025), please arrange OMDB VIP LOUNGE"
MUST Generate:
- OMDB Ground-Handling (auto for intermediate landing)
- OMDB Airport-Fees (auto for intermediate landing)
- OMDB VIP-Lounge (explicitly requested)
- HJKJ Ground-Handling (auto for final destination)  
- HJKJ Airport-Fees (auto for final destination)
- NO services for FZAA (origin airport only)
