If you had any doubts about moving your website to a truly responsive platform (not half-way made up technologies) check out this article:
The article mentions that “Delta is just following market trends” just like Target had discontinued its iPad app in 2016:
“Target discontinued its iPad app after six years, noting that it had improved its website to create a more streamlined shopping experience across all devices.”
That short paragraph encompasses all the power of a fully responsive platform; a streamlined experience in all devices. The experience must translate to all parts of the site, including both the main content (usually product sales and company information) but also secondary (blog, content, and product information).
Secondary content is not always responsive in all platforms.
