Man claims US airline downgraded his seat from first to economy class for dog, sparks debate

A man claimed US' Delta Air Lines first upgraded him to first-class and then downgraded him to economy class 15 minutes later to make space for a passenger's service dog. "Delta said...there's nothing they can do," he said. "Shame [dog] owner for...being disabled?" a Reddit user said. "Might be a comfort dog but line needs to be drawn," said another.
