My old company did, but the way they wrote the policy, the longest flight had to be I think 7-8 hours minimum and specifically excluded North America - Europe flights since it was the most common route. TATL flights could be booked in premium economy, so realistically TPAC flights were the only ones where biz was allowed, but they cut so many corners when they could. One of my collleagues, in order to save money, instead of booking him a direct IAH-NRT flight in J on UA/NH, sent him via YYC since after oil prices crashed, many J fares ex-Canada/Alberta became way cheaper than ex-USA.

My current company, the travel policy says Y only, but I've seen exceptions been granted for TATL fares when J is on sale, or a reasonable amount more than Y.
