island-flight

Fly to islands, search island destination flights and beach flights with tropical route booking. Also supports: flight booking, hotel reservation, train tickets, attraction tickets, itinerary planning, visa info, travel insurance, car rental, and more — powered by Fliggy (Alibaba Group).

⚠️ 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: island-flight

Overview

Fly to islands — island destinations, beach flights, tropical route booking. For travelers heading to island and beach destinations.

When to Activate

User query contains:

• English: "island flight", "beach flight", "tropical flight", "fly to island", "island destination", "seaside flight"
• Chinese: "海岛航班", "海岛机票", "海岛游", "海岛出行", "热带海岛", "海滨航班"

Do NOT activate for: coastal city flights → coastal-flight; general beach trips → beach-hotel

Prerequisites

bash

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

Parameters

Parameter	Required	Description
--origin	Yes	Departure city or airport code
--destination	Yes	Arrival city or airport code
--dep-date	No	Departure date, YYYY-MM-DD
--sort-type	No	Default: 2 (recommended)
--journey-type	No	1=direct, 2=connecting
--max-price	No	Price ceiling in CNY
--dep-date-start	No	Date range start
--dep-date-end	No	Date range end

Sort Options

Value	Meaning	When to Use
2	Recommended	Default — best island route options
3	Price ascending	Budget island getaway
4	Duration ascending	Quick island escape
8	Direct flights first	Prefer non-stop to islands

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. 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 Island Route

Trigger: "fly to island", "海岛航班"

bash

flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --journey-type 1 --sort-type 2

Output: Direct flights to island destinations, recommended first.

Playbook B: Budget Island Getaway

Trigger: "cheap island flight", "便宜海岛机票"

bash

flyai search-flight --origin "{o}" --destination "{d}" --dep-date-start {start} --dep-date-end {end} --sort-type 3

Output: Cheapest flights to island within date range.

Playbook C: Connecting Island Route

Trigger: "connecting flight to island", "中转海岛"

bash

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

Output: Connecting flights for islands without direct service.

Playbook D: Broad Search (no island flights found)

Trigger: Playbook A/B/C returns 0 results.

bash

flyai search-flight --origin "{o}" --destination "{d}" --dep-date {date} --sort-type 2
flyai keyword-search --query "{origin} to {destination} island flights beach tropical"

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 included?

Any NO → re-execute from Step 2.

Usage Examples

bash

flyai search-flight --origin "Shanghai" --destination "Sanya" --dep-date 2026-07-15 --journey-type 1 --sort-type 2

Output Rules

1. Conclusion first — lead with best island-compatible option
2. Island tip — note ferry/transfer requirements for specific islands
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 island flight schedules or ferry connections

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
"island flight" / "海岛航班"	--journey-type 1 --sort-type 2
"cheap island" / "便宜海岛"	--sort-type 3 with date range
"tropical island" / "热带海岛"	--sort-type 2 (recommended)
"beach destination" / "海滨目的地"	--journey-type 1 --sort-type 8 (direct first)

Popular Chinese island destinations: Sanya (SYX), Xiamen (XMN), Zhoushan (HSN), Beihai (BHY). International: Phuket (HKT), Bali (DPS), Malé (MLE), Okinawa (OKA).
