I work for a fortune 50 company you will have heard of. Our revenues are in the 10's of billions range.
Recently, it came down that only VP and above could book biz, and only on flights more than 8 hours. Everyone else, gets coach NO MATTER HOW LONG THE FLIGHT. And we fly to Asia, South America, Europe and the Middle East frequently.
The days of biz travel for biz travelers seems to be over, unless you are getting ug's from your own miles. If you get to keep them that is.
