A genuine and very serious warning regarding your enthusiasm for such a company.
Please use our search facilty to find out for yourselves the hole you'd be digging for yourselves regarding flying hours even if such an opportunity should present itself.
This is no criticism of a company like DHL or the equipment they fly. No matter how attractive the company, the training, and the idea of a big jet are to you the glacial annual total of flying hours versus duty hours worked will hinder your career.
Please don't believe me - go and find out for yourselves.

Rob
