Today on AA's Facebook page, they have a pic of one of their Premium cabins with the phrase: "We’re winging our way to the Aircraft Interiors Expo in Hamburg, Germany with plans for a big reveal. Any guesses? Stay tuned." Some have speculated that AA will be ordering some A350's or A380's because of being in Hamburg, while others have commented that AA will be upgrading some of their other Premium Cabins on other aircraft. Thoughts?
