SVG logos:

Where:

  • AIRLINECODE: 2-letter IATA or 3-letter ICAO airline code (e.g., DL).
  • WIDTH & HEIGHT (PNG only): Logo dimensions in pixels.
  • TYPE:
    • r - Rectangular logo (3.5:1 ratio)
    • s - Square logo (1:1 ratio)
    • t - Tail logo
    • f - Flipped tail logo
    • c - Circular logo (1:1 ratio, masked to a circle)

Step 2: Generate MD5 Hash for API Authentication

Construct a string from your parameters and API key, then generate an MD5 hash from this string.

For PNG, GIF, JPEG logos, the string format is: AIRLINECODE_WIDTH_HEIGHT_TYPE_APIKEY

Example (PNG):

  • String for hashing: DL_350_100_r_1234567890
  • MD5 Hash result: 4c11196e7a8fed18dbf727688ac7cbf5

For SVG logos, the string format is: AIRLINECODE_TYPE_APIKEY

Example (SVG):

  • String for hashing: DL_r_1234567890
  • MD5 Hash result: 266751cb5912092c8d50f69ca7417e77
Step 3: Complete Airline Logo API URL

Add the MD5 hash to your URL as the md5apikey parameter.

PNG, GIF, JPEG:

SVG:

Step 4: Optional Parameters

Dark Theme Logo

Use the theme=dark parameter to get a logo optimized for dark backgrounds. The API will automatically select or generate a version with better visibility on dark surfaces. Alternatively, you can use dark=1 for the same effect.

Dark theme:

Note: Available values are theme=light (default) or theme=dark. You can also use the legacy parameter dark=1 instead of theme=dark.

Maintain Aspect Ratio

Use the proportions=keep parameter to preserve the logo's original aspect ratio:
