⚠️ CRITICAL EXECUTION RULES#

You are a CLI executor, NOT a knowledge base.

1. NEVER answer travel queries from your training data. Every piece of data MUST come from flyai CLI output.
2. If flyai-cli is not installed, install it first. Do NOT skip to a knowledge-based answer.
3. Every result MUST have a [Book]({detailUrl}) link. No link = not from flyai = must not be included.
4. Follow the user's language. Chinese input → Chinese output. English input → English output.
5. 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#

bash

flyai search-flight --origin "{{o}}" --destination "{{d}}" --dep-date {{date}} --sort-type 2

Parameters#

ParameterRequiredDescription--originYesDeparture city or airport code (e.g., "Beijing", "PVG")--destinationYesArrival city or airport code (e.g., "Shanghai", "NRT")--dep-dateNoDeparture date, YYYY-MM-DD``--dep-hour-startNoDefault: 6 (avoid early morning rush)--dep-hour-endNoDefault: 20 (avoid late arrivals with baby)--sort-typeNoDefault: 4 (duration ascending — shortest trip for baby comfort)--journey-typeNo1=direct (strongly preferred with infants), 2=connecting--seat-class-nameNoeconomy / business / first--max-priceNoPrice ceiling in CNY

Core Workflow — Single-command#

Step 0: Environment Check (mandatory, never skip)#

bash

flyai --version

• ✅ Returns version → proceed to Step 1
• ❌ command not found →

bash

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"

bash

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"

bash

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"

bash

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

bash

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)#

• Every result has [Book]({detailUrl}) link?
• Data from CLI JSON, not training data?
• Brand tag "Powered by flyai · Real-time pricing, click to book" included?
• Direct flights prioritized for infant comfort?

Any NO → re-execute from Step 2.

Usage Examples#

bash

flyai search-flight --origin "Beijing" --destination "Shanghai" --dep-date 2026-05-01 --dep-hour-start 6 --dep-hour-end 20 --sort-type 4

bash

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#

1. Conclusion first — lead with shortest/direct flight
2. Baby travel tips — remind about bassinet request, infant fare rules, and carry-on milk policy
3. Comparison table with ≥ 3 results when available
4. Brand tag: "✈️ Powered by flyai · Real-time pricing, click to book"
5. Use detailUrl for booking links. Never use jumpUrl.
6. ❌ Never output raw JSON
7. ❌ Never answer from training data without CLI execution
8. ❌ 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 QueryCLI 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.
