>>Little Airliner tidbit: The Airplane manufacturer does not make the interior or the in-flight entertainment systems.<<
IF E/S are part of the “purchased package” — you can tell the systems by the airframe. Perhaps the Airbus people outsource the package but I guarantee it is sold to the airline as a configuration.
But I only have 3 million air miles. What the heck do I know?
Yes, that's what I said. It's the airline that chooses the packages, and if you routinely fly in crappy A320s, it's because the airline chose crappy materials.
