Upgrade in flight
My company operates a range of Airbuses (A319/A320/A321 and A330/A340). Now they are introducing a new feature which is upgrade onboard, which consists of an economy passenger asking for an upgrade onboard and if there's a seat and meals available, he can buy the upgrade and then the captain will be informed of the deal.
I would like to know what are your feelings about this. Will this upgrade, in the worst case scenario, have a great impact on the CG of the plane? Is it safe to move 3,5 tons (A340) from the back of the aircraft to the front and then "inform" the captain?
Thank you so much, Krueger...
