When I was corporate we always flew business if the flight was “over an ocean”. These tickets were usually booked last minute, so very costly. I got super accustomed to the accommodations and service in BizClass, especially Cathay Pacific and believe it or not, Air Canada, both of whom’s international Biz Class is on par with most other first class (individual pod seating)… that said, I flew to Shanghai coach for the first time, and I didn’t think it was that bad.

Room sharing is against many corporate HR policies. I’ve never had to do it in my entire career, even as a junior designer at a small firm. I did get to share a massive suite though, which had multiple bedrooms. I know some researchers prefer room sharing for research immersion trips. After presenting to a client, or a day spent at the factory, I need some space to clear my head.
