npm install airlinefyi

Works in Node.js, Deno, Bun, and browsers (ESM).

import { AirlineFYI } from "airlinefyi";

const api = new AirlineFYI();

// Look up an airline by slug
const airline = await api.getAirline("korean-air");
console.log(airline);
// Airline details: name, IATA code, alliance, hub airports, fleet size

// Search across all airline content
const results = await api.search("star alliance");
console.log(results);

The world's airlines operate within a complex ecosystem of alliances, codeshare agreements, and joint ventures. The three major alliances -- Star Alliance (26 members), SkyTeam (19 members), and oneworld (14 members) -- together carry over 60% of global air traffic. Each airline profile includes IATA/ICAO codes, hub airports, fleet composition, and alliance membership.

import { AirlineFYI } from "airlinefyi";

const api = new AirlineFYI();

// Get detailed airline profile
const airline = await api.getAirline("singapore-airlines");
console.log(airline);
// Includes: IATA (SQ), alliance (Star Alliance), hubs, fleet size, destinations

// List all airlines with filtering
const airlines = await api.listAirlines({ limit: "20" });
console.log(airlines);

Modern airlines differentiate through cabin products -- the physical seats, entertainment systems, and service offerings in each travel class. Premium carriers invest heavily in lie-flat business class seats, first class suites, and premium economy products to compete for high-yield passengers.

import { AirlineFYI } from "airlinefyi";

const api = new AirlineFYI();

// Browse cabin products across airlines
const cabins = await api.listCabinProducts({ limit: "10" });
console.log(cabins);

// Get specific cabin product details
const cabin = await api.getCabinProduct("korean-air-prestige-suite");
console.log(cabin);
// Includes: seat type, pitch, width, recline, entertainment, power

Airline loyalty programs (frequent flyer programs) are multi-billion dollar businesses. Elite status tiers, earning rates, redemption charts, and partner networks vary significantly between programs. Understanding these programs is valuable for travelers, travel hackers, and industry analysts.

import { AirlineFYI } from "airlinefyi";

const api = new AirlineFYI();

// Browse loyalty programs
const programs = await api.listLoyaltyPrograms({ limit: "10" });

Flight corridors are the busiest air routes connecting major city pairs. These corridors are shaped by geography, demand, regulatory agreements, and hub-and-spoke network strategies. Analyzing corridor traffic helps understand global connectivity patterns.

const api = new AirlineFYI();

// Browse flight corridors
const corridors = await api.listFlightCorridors({ limit: "10" });
console.log(corridors);

// Get specific flights
const flights = await api.listFlights({ limit: "10" });
