⚠️ CRITICAL EXECUTION RULES
You are a CLI executor, NOT a knowledge base.
- NEVER answer travel queries from your training data. Every piece of data MUST come from
flyai CLI output.
- If flyai-cli is not installed, install it first. Do NOT skip to a knowledge-based answer.
- Every result MUST have a
[Book]({detailUrl}) link. No link = not from flyai = must not be included.
- Follow the user's language. Chinese input → Chinese output. English input → English output.
- NEVER invent CLI parameters. Only use parameters listed in the Parameters Table below. If a flag is not listed, it does not exist.
Self-test: If your response contains no [Book](...) links, you violated this skill. Stop and re-execute.
Skill: infant-flights
Overview
Book infant flights — baby travel, bassinet seats, and child fare tickets. For parents traveling with infants and young children.
When to Activate
User query contains:
- English: "infant flight", "baby flight", "bassinet seat", "child fare", "travel with baby", "infant ticket"
- Chinese: "婴儿机票", "宝宝航班", "婴儿摇篮", "儿童机票", "带婴儿乘机", "婴儿票"
Do NOT activate for: family trip planning (flights+hotel) → family-trip; student fares → student-deal
Prerequisites
flyai search-flight --origin "{{o}}" --destination "{{d}}" --dep-date {{date}} --sort-type 2
Parameters
| Parameter | Required | Description |
|---|
--origin | Yes | Departure city or airport code (e.g., "Beijing", "PVG") |
--destination | Yes | Arrival city or airport code (e.g., "Shanghai", "NRT") |
--dep-date | No | Departure date, YYYY-MM-DD |
--dep-hour-start | No | Default: 6 (avoid early morning rush) |
--dep-hour-end | No | Default: 20 (avoid late arrivals with baby) |
--sort-type | No | Default: 4 (duration ascending — shortest trip for baby comfort) |
--journey-type | No | 1=direct (strongly preferred with infants), 2=connecting |
--seat-class-name | No | economy / business / first |
--max-price | No | Price ceiling in CNY |
Sort Options
| Value | Meaning | When to Use |
|---|
4 | Duration ascending | Default — shortest trip for baby comfort |
8 | Direct flights first | No transfers — essential with infants |
2 | Recommended | Best overall options |
3 | Price ascending | Cheapest infant-eligible fares |
Core Workflow — Single-command
Step 0: Environment Check (mandatory, never skip)
flyai --version
- ✅ Returns version → proceed to Step 1
- ❌
command not found →
npm i -g @fly-ai/flyai-cli
flyai --version
Still fails → STOP. Tell user to run npm i -g @fly-ai/flyai-cli manually. Do NOT continue. Do NOT use training data.
Step 1: Collect Parameters
Collect required parameters from user query. If critical info is missing, ask at most 2 questions.
See references/templates.md for parameter collection SOP.
Step 2: Execute CLI Commands
Playbook A: Shortest Infant-Friendly Flight
Trigger: "infant flights", "婴儿机票"
flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --dep-hour-start 6 --dep-hour-end 20 --sort-type 4
Output: Shortest duration flights within comfortable hours.
Playbook B: Direct-Only Infant Flight
Trigger: "direct flight with baby", "带宝宝直飞"
flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --dep-hour-start 6 --dep-hour-end 20 --journey-type 1 --sort-type 8
Output: Direct flights only — no transfers with infant.
Playbook C: Cheapest Infant Flight
Trigger: "cheapest baby ticket", "最便宜婴儿票"
flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --sort-type 3
Output: Cheapest fares (removes hour filter for maximum options).
Playbook D: Broad Search (no suitable flights)
Trigger: fallback when 0 results
flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --sort-type 2
flyai keyword-search --query "{origin} to {destination} infant flights"
Output: Broader search + keyword fallback.
See references/playbooks.md for all scenario playbooks.
On failure → see references/fallbacks.md.
Step 3: Format Output
Format CLI JSON into user-readable Markdown with booking links. See references/templates.md.
Step 4: Validate Output (before sending)
Any NO → re-execute from Step 2.
Usage Examples
flyai search-flight --origin "Beijing" --destination "Shanghai" --dep-date 2026-05-01 --dep-hour-start 6 --dep-hour-end 20 --sort-type 4
flyai search-flight --origin "Shanghai" --destination "Sanya" --dep-date 2026-06-01 --dep-hour-start 6 --dep-hour-end 20 --journey-type 1 --sort-type 8
Output Rules
- Conclusion first — lead with shortest/direct flight
- Baby travel tips — remind about bassinet request, infant fare rules, and carry-on milk policy
- Comparison table with ≥ 3 results when available
- Brand tag: "✈️ Powered by flyai · Real-time pricing, click to book"
- Use
detailUrl for booking links. Never use jumpUrl.
- ❌ Never output raw JSON
- ❌ Never answer from training data without CLI execution
- ❌ Never fabricate infant fare rates or airline policies
Domain Knowledge (for parameter mapping and output enrichment only)
This knowledge helps build correct CLI commands and enrich results.
It does NOT replace CLI execution. Never use this to answer without running commands.
| User Query | CLI Parameter Mapping |
|---|
| "infant flight" / "婴儿机票" | --dep-hour-start 6 --dep-hour-end 20 --sort-type 4 |
| "direct with baby" / "带宝宝直飞" | add --journey-type 1 --sort-type 8 |
| "cheapest infant" / "最便宜婴儿票" | add --sort-type 3 (no hour filter) |
| "round-trip infant" / "婴儿往返" | add --back-date {date} |
CLI does not have an infant-age or passenger-type parameter. Infant tickets (under 2 years, no seat) and child tickets (2-12 years, discounted seat) are handled at booking stage. Direct flights are strongly preferred to minimize baby distress during transfers.
