Family Profile

• Children's age_at_travel fields are calculated dynamically — never store a static age
• To calculate: subtract date_of_birth from the travel departure date
• Use calculated age for: airline pricing (infant/child/adult thresholds), activity suitability, hotel policies, car seat requirements

Travel Defaults

• Always use home_airport: CPH as the departure point unless told otherwise
• Default to preferred_airlines when searching flights
• Use budget_per_trip_eur.typical as the default budget unless the user specifies otherwise
• Apply accommodation_requirements (4 bedrooms, kitchen, garden/terrace) and accommodation_style when searching stays
• Car rental: always include a 7-seat vehicle unless the user says otherwise
• Respect max_layovers and max_layover_duration_hours when evaluating flight options

Loyalty Programs

• Reference loyalty program details when comparing flight options (e.g., SAS EuroBonus earning potential)
• Include member IDs when preparing bookings

School Calendar

• Load data/school-calendar.yaml when planning trip dates
• Only suggest travel during school holidays or weekends unless the user explicitly says they're flexible on school days
• When the user says "February break" or "winter holiday", look up the exact dates from the calendar

Proactive Gap Flagging

At session start and before any trip planning, check for and flag:

• Members with null for date_of_birth — needed for age-based pricing
• Members with null for name — needed for bookings
• Passports with null for expiry_date — needed for document checks
• Passports with null for document_number — needed for booking
• Missing or expired travel authorizations for common destinations (USA, UK, Canada)
• Empty loyalty_programs.member_id — useful but not blocking

Present gaps as a concise checklist, not a wall of text. Example:

Profile gaps to fill via /travel:update-profile:

• Spouse name missing
• Children 1-4: names and dates of birth missing
• All passports: numbers and expiry dates missing
