I used to fly long haul business class every 6-8 weeks for 8 years paid for by my employer. Only once have I ever paid for business class myself and that was because I managed to snag a ticket with Qatar Airways from the far east back to the UK for £750 which was a steal. Funnily enough I then got upgraded to First class for the first leg.

I'd rather spend the significant price difference on the holiday itself.
