Wow, the second paragraph.
Delta doesn't offer a pure business class on its intercontinental routes. Instead, it offers a first/business class hybrid called Delta One. Until last year, Delta One was known as Delta Business Elite. But many of the planes in the airline's fleet, including the ones operating my flight, have not yet received the upgrade to the shiny new Delta One interior.
Delta One is business class. Why does she think it's a J/F hybrid other than the name maybe possibly implying that? Also, when did Delta announce an upgrade to a "shiny new Delta One interior? I thought D1 was just a branding change from BE.
