That is a purposefully done photo shoot. The C+ picture was also purposefully done by marketing. However the fact that a drop down covers a part of the picture isn't really something marketing can account for. In this case some part of the picture will always be covered. Click on flight status and its quite obvious it's just a matter of a dropdown covering part. The picture wasn't purposefully done to make it appear like twice the legroom. Simply a side effect from using one specific drop down tab. Happens on tons of websites.

Two different teams, two different purposes. One to market the product, one to create a useable website. Different from a ceral box where marketing the product is only thing happening.
