border-flight

Search cross-border flights, international departures and visa-required routes with overseas travel 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: border-flight

Overview

Cross-border flights — international departures, visa-required routes, overseas travel. For travelers flying internationally across borders.

When to Activate

User query contains:

• English: "border flight", "cross-border flight", "international departure", "overseas flight", "visa-required flight", "outbound flight"
• Chinese: "跨境航班", "国际航班", "出境航班", "出国机票", "海外航班", "出港航班"

Do NOT activate for: domestic flights → economy-flights; connecting flights → connecting

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 international options
3	Price ascending	Budget international travel
4	Duration ascending	Fastest international route
8	Direct flights first	Prefer non-stop international

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 International Route

Trigger: "international flight", "国际航班"

bash

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

Output: Recommended international flights.

Playbook B: Budget International Travel

Trigger: "cheap international flight", "便宜国际机票"

bash

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

Output: Cheapest international flights within date range.

Playbook C: Direct International Flight

Trigger: "direct international flight", "国际直飞"

bash

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

Output: Direct international flights.

Playbook D: Broad Search (no international 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} international 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 included?

Any NO → re-execute from Step 2.

Usage Examples

bash

flyai search-flight --origin "Shanghai" --destination "Tokyo" --dep-date 2026-06-01 --sort-type 2

Output Rules

1. Conclusion first — lead with best international option
2. Visa reminder — note visa requirements for the destination country
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 visa policies or entry 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 Query	CLI Parameter Mapping
"international flight" / "国际航班"	--sort-type 2
"cheap overseas" / "便宜出国"	--sort-type 3 with date range
"direct international" / "国际直飞"	--journey-type 1 --sort-type 8
"outbound flight" / "出境航班"	--sort-type 2

Major Chinese international hubs: PEK, PVG, CAN, SZX, CTU. CLI does not have a border/customs filter — all results are regular flights.
