Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by borski on GitHub. Read the source before you install it.

Installation

Install the Cabin Codes AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/borski/travel-hacking-toolkit/tree/main/plugins/travel-hacking-toolkit/skills/cabin-codes
Enable the skill in any chat where you want it available.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/borski/travel-hacking-toolkit.git /tmp/travel-hacking-toolkit
mkdir -p .claude/skills
cp -r /tmp/travel-hacking-toolkit/plugins/travel-hacking-toolkit/skills/cabin-codes .claude/skills/cabin-codes

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Cabin Codes in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Cabin Codes on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Cabin Codes is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Cabin Codes

When reading Seats.aero results or discussing award inventory, these cabin codes appear:

Code	Cabin	Notes
F	First Class	Includes true first class suites
J	Business Class	Lie-flat seats on long-haul
W	Premium Economy	Also sometimes coded as "P"
Y	Economy	Standard seating

Fare Class Codes for Saver Awards

These are critical for partner bookings. If you see these fare codes available on united.com (or equivalent), the flight is bookable through partner programs at their (often lower) rates.

Code	Meaning	Programs That Use It
X	Economy Saver	United MileagePlus, bookable through partners
I	Business Saver	United MileagePlus, bookable through Turkish M&S and others
O	First Saver	United MileagePlus

Why This Matters

Partner award rates are often dramatically lower than the operating airline's own rates. United business saver (I class) bookable through Turkish Miles&Smiles is a classic example: a route that costs 80,000 United miles might only cost 45,000 Turkish miles. But Turkish (and other partners) only sees the saver inventory. If only "standard" or "everyday" fares show on united.com, partners cannot book that flight.

When checking award availability for a flight you found on a partner program (Turkish, Aeroplan, ANA, etc.), verify the saver class is open on the operating airline's site before transferring points.

Frequently asked questions

What does the Cabin Codes AI skill do?

IATA cabin codes (F/J/W/Y) and saver fare class codes (X/I/O) for reading award inventory and determining partner-bookable availability.

Why use Cabin Codes on TypingMind?

Because you install it once and use it with any model. Cabin Codes is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Cabin Codes in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/borski/travel-hacking-toolkit/tree/main/plugins/travel-hacking-toolkit/skills/cabin-codes. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Cabin Codes?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Cabin Codes?

As many as you like. As long as a model supports skills, you can use Cabin Codes with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Cabin Codes AI skill free?

Yes. It is published on GitHub by borski under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
