Airline Information

The Travelese Engine API uses IATA airline codes to identify carriers in requests and responses. This guide provides information about airline codes and how they are used in the API.

​

IATA Airline Codes

IATA (International Air Transport Association) airline codes are two-letter codes used to identify airlines worldwide. For example:

• BA: British Airways
• AA: American Airlines
• EK: Emirates
• SQ: Singapore Airlines
• LH: Lufthansa

​

Using Airline Codes

Airline codes appear in various API responses:

1. Flight Segments: In flight segment information:

   {
     "marketingCarrierCode": "BA",
     "airlineName": "BRITISH AIRWAYS",
     "flightNumber": "175"
   }
   

2. Codeshare Information: When flights are operated by partner airlines:

   {
     "marketingCarrierCode": "BA",
     "operatingCarrierCode": "AA",
     "flightNumber": "6175"
   }

Airline Information in Responses

When an airline appears in API responses, it typically includes:

{
  "marketingCarrierCode": "BA",  // IATA code
  "airlineName": "BRITISH AIRWAYS", // Full name
  "flightNumber": "175",         // Flight number
  "aircraft": {
    "code": "77W",              // Aircraft type code
    "name": "BOEING 777-300ER"  // Aircraft name
  }
}

​

Codeshare Flights

A codeshare flight is operated by one airline but marketed by another. In the API:

1. marketingCarrierCode: The airline selling the ticket
2. operatingCarrierCode: The airline actually operating the flight
3. flightNumber: Usually includes the marketing carrier’s code

Example:

{
  "marketingCarrierCode": "BA",    // British Airways
  "operatingCarrierCode": "AA",    // American Airlines
  "flightNumber": "BA6175",        // British Airways flight number
  "airlineName": "BRITISH AIRWAYS"
}

​

Best Practices

1. Display Names: Always show both the airline code and full name to users
2. Codeshare Awareness: Consider displaying both marketing and operating carrier information
3. Flight Numbers: Include the full flight number with airline code prefix

​

Common Issues

1. Codeshare Confusion: Users may be unfamiliar with codeshare operations
2. Airline Alliances: Some routes may involve multiple alliance partners
3. Schedule Changes: Airlines may change flight numbers or routes

​

Finding Airline Codes

To find the correct IATA code for an airline:

1. Use the official IATA Airline Codes Directory
2. Check the airline’s official website
3. Use online flight search engines that display IATA codes
