Current organisation: international travel banned (public sector, "no need to have it")
Previous: 1000 staff educational organisation; business if you were executive, decent economy for the rest of us. Bear in mind NZ is a long way from everywhere so cheap flights... nope.

I've done a fair bit of number crunching and actually worked out most of the time it makes more sense to (a) book economy, (b) have extra 'non productive time' i.e. more "holiday days", and (c) just book hotels for that extra time, than book business. The cost saving is likely to exceed the productivity loss from less time due to business (I think most of the time for NZ, the salary had to be $500k NZD or so to make business class make sense - it was actually cheaper to send people on mini-holidays. That's approx $320k USD.)
