Only Atlas aircraft leased out for a longer period are painted in the colours of the customer.
Atlas Aircraft fly in China Airlines, Emirates and since two months, in Eva Air livery.
The BA aircraft had to be repainted because of legal reasons. Thats why Atlas created the subsidiary Global Supply Systems for them.
The Alitalia aircraft that flew almost two years for them was painted in a 50% complete livery (only tail and titles, no cheatline).
The TNT aircraft was once rumoured to be dressed in the stunning orange colours. Unfortunately that hasn´t been the case yet.
