If you've ever been frustrated by airport gate agents who ignore you, misunderstand you or generally make your life miserable before you even get on the plane, then don't fly through Orly Airport in Paris.
The airport is currently testing out "virtual" boarding agents -- holograms that welcome passengers and provide flight information.
The holograms are projections of real-life agents, except they don't talk back. Which, depending on the situation, could be even more annoying than the flesh-and-blood ones who do. There's no winning, people.
