⚠️ 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: student-deal#

Overview#

Find student flight discounts — under-26 fares, student verification, and youth travel deals. For students who want the cheapest flights with flexible booking.

When to Activate#

User query contains:

• English: "student flight", "student discount", "under 26 fare", "youth ticket", "student airfare", "budget student flight"
• Chinese: "学生机票", "学生折扣", "26岁以下机票", "青年机票", "学生特价", "学生票"

Do NOT activate for: military fares → military-flights; senior fares → senior-flights; general budget → economy-flights

Prerequisites#

bash

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

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: Cheapest Student Flight#

Trigger: "student flights", "学生机票"

bash

flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --seat-class-name economy --sort-type 3

Output: Cheapest economy flights sorted by price.

Playbook B: Flexible Date Student Deal#

Trigger: "cheapest student flight any day", "学生哪天最便宜"

bash

flyai search-flight --origin "{o}" --destination "{d}" --dep-date-start "{date-7}" --dep-date-end "{date+7}" --seat-class-name economy --sort-type 3

Output: Cheapest flights across a 15-day window.

Playbook C: Budget-Capped Student Flight#

Trigger: "student flight under ¥{price}", "{price}以内的学生票"

bash

flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --seat-class-name economy --max-price {budget} --sort-type 3

Output: Economy flights within student budget.

Playbook D: Broad Search (no student deals found)#

Trigger: fallback when 0 results

bash

flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --sort-type 3
flyai keyword-search --query "{origin} to {destination} student discount flights"

Output: Broader search without seat-class filter + 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?
• Results sorted by price (cheapest first)?

Any NO → re-execute from Step 2.

Usage Examples#

bash

flyai search-flight --origin "Beijing" --destination "Chengdu" --dep-date 2026-09-01 --seat-class-name economy --sort-type 3

bash

flyai search-flight --origin "Shanghai" --destination "Xiamen" --dep-date-start 2026-07-01 --dep-date-end 2026-07-15 --seat-class-name economy --sort-type 3

Output Rules#

1. Conclusion first — lead with cheapest student-eligible fare
2. Student tips — remind about student verification and flexible rebooking
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 student discount rates or verification requirements

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"student flight" / "学生机票"--seat-class-name economy --sort-type 3"flexible date student" / "日期灵活学生"add --dep-date-start "{date-7}" --dep-date-end "{date+7}""under budget" / "预算内学生票"add --max-price {budget}"round-trip student" / "学生往返"add --back-date {date}

CLI does not have a student-verification parameter. Student discounts are applied at booking stage with ID verification. Mid-week and off-peak flights typically offer the best student deals. Flexible date searches (±7 days) maximize savings.
