Be aware that DHL runs 2 airlines in Europe. DHL Air, and EAT. FTLs are different and DHL Air are restricted by CAP 371 (with some variations) and do not fly for more than 12 hours. As has been said, people are working hard at the moment, noone will try to hide that, but I find it does suit my life well, and normally get to see plenty of my (very young) family.
I work for DHL Air. It has its issues for sure, and some that some are leaving over, put you makes your own choices about what will suit you the best. Listen very carefully to what is said in these pages, some is severely over stated. As I said the issues that have been mentioned elsewhere are concerning, but for me the lifestyle has and will, I am sure be again, reasonable compemsation
