"Business travellers care more about upgrades and high fares than security according to a recent survey.
In a survey that questioned 450 frequent flyers about their air travel concerns, a quarter said they would travel more often if they were offered upgrades. "
This suggests to me that this is nothing to do with business travel. Surely there is either a business need to travel or there isnt. Why would you fly more if there was no need to do so, upgrade or no upgrade
