⚠️ 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: first-class
Overview
Book first class flights — premium cabins with lie-flat seats, priority boarding, and airport lounge access. For travelers who value comfort and exclusivity over price.
When to Activate
User query contains:
- English: "first class", "premium cabin", "lie-flat seat", "luxury flight", "VIP flight", "top tier cabin"
- Chinese: "头等舱", "豪华舱", "VIP机票", "最高舱位", "平躺座位", "贵宾航班"
Do NOT activate for: business class → business-flights

2 | Recommended | Default — best first class options |
3 | Price ascending | Compare first class pricing |
4 | Duration ascending | Fastest premium route |
8 | Direct flights first | Non-stop first class only |
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: Recommended First Class
Trigger: "first class flights", "头等舱机票"
flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --seat-class-name first --sort-type 2
Output: Best first class options sorted by recommendation.
Playbook B: Cheapest First Class
Trigger: "cheapest first class", "最便宜的头等舱"
flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --seat-class-name first --sort-type 3
Output: First class flights sorted by lowest price.
Playbook C: Direct First Class Only
Trigger: "direct first class", "直飞头等舱"
flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --seat-class-name first --journey-type 1 --sort-type 4
Output: Non-stop first class flights, fastest duration first.
Playbook D: Broad Search (no first class found)
Trigger: fallback when 0 results
flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --seat-class-name first --sort-type 2
flyai keyword-search --query "{origin} to {destination} first class 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 --seat-class-name first --sort-type 2
flyai search-flight --origin "Shanghai" --destination "Tokyo" --dep-date 2026-06-01 --seat-class-name first --journey-type 1 --sort-type 4
Output Rules
- Conclusion first — lead with best or cheapest first class option
- 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 prices, flight numbers, or cabin details
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 |
|---|
| "first class" / "头等舱" | --seat-class-name first |
| "cheapest first class" / "最便宜头等舱" | add --sort-type 3 |
| "direct first class" / "直飞头等舱" | add --journey-type 1 --sort-type 4 |
| "round-trip first class" / "往返头等舱" | add --back-date {date} |
First class availability varies by route. Domestic trunk routes (BJ-SH, BJ-GZ) typically have 2-4 first class seats per flight. International long-haul may offer lie-flat suites. If 0 results, suggest business class as alternative.
