Captainprop,
As you may have probably guessed, you're friends and colleagues are talking rubbish.
I know that fuel purchasing, Insurance and other areas were homogenised from day 1.
Just because you bump into someone who works for a company, don't assume they know what is going on at board level.
Luxaviation are letting each company keep it's own company culture whilst also having the economies of scale in the purchasing side - a refreshing approach if you ask me.
