The lie-flat pod. I traveled through Tokyo to Bangkok over the Holidays-and-no-there were no pods. Just the old seats (Bangkok had the even older recliner seats). Kinda surprised as the JFK-Tokyo is the most expensive flight Delta offers in Biz. Why would you not have the most upgraded plane on that route?

Will be going back to Bangkok around July 4th and was hoping that the pods would be in place by then.
