I'm taking a shot in the dark here but did the shipment come from Ecuador or Florida? I know one of the popular Ecuadorian vendors opened US branch in FL within the past few months. Either way, anytime I get an imported bare root plant either shipped direct or from a show (which was obviously also shipped) the first thing I do when I get them home is just let them soak in water bare root for 48 hours to help them re-hydrate before I pot them.
Specifically to the Aerides, I've never seen one potted but I guess you could. To Zain's point, mine gets misted for 10 minutes two times a day and it's just hanging bare root so the roots can dry fully in between watering. The roots really need air which is another reason I'd be leery of potting it.
