Actually, World Airline News doesn’t own the picture. As you can read at the end of their article, it says Copyright Photo: TMK Photography/AirlinersGallery.com. If you search further, you’ll find this on the original website:
All photos are copyrighted by the individual photographer. No copyright image may be used without prior written approval. Once approved, the image must have the proper credit line and the photo links retained.
I recommend you to at least mention the correct owner and link it to the website above. Thanks!
