The brand-new long-haul Delta fleet will have the brand's debut Delta One first class suites. And for once, the airline isn't exaggerating with the name. Each one — there will be 32 per plane — has a full-height door for complete privacy. Lest you think it'll be like traveling in a broom closet, know that it has an open top, enough room to lay down, and comes with an entire entertainment suite.
