I fly corporate and it comprises everything besides the actual flying: flightplanning, organising catering, checking the bills, organising/monitoring maintenance events, cleaning the aircraft, update for e-charts/FMS etc.
As the meetings where we fly to are mainly from monday to friday, thatīs when I fly so the weekend is almost always free for social activities. The downside is that there can be weeks without flying! All in all, itīs ok!
