When I first started traveling for work 10 years ago I thought it was nuts to pay $8K-$10K for tickets, and usually just had the company buy coach tickets for $1800-$2k. My thinking was that for the 12-14 hour flights, it seemed to my naive mind that spending an extra $6k was "wasteful". After many years of traveling north of 100K miles/year, trust me, traveling in coach sucks, and anytime I'm forced to do so I'm miserable. If I had the money, I would never, ever, take any flight > 6-10 hours in coach.
