Hmmm, this could be maintenance issue. I know LH Cargo (LH Technik) are screaming for B1/B2 Engineers with the MD11 PW4000/CF6 ratings.
And they are like feckin hens teeth at this point...Particularly the Pratts.
Martinair are also crying out for Engineers. just aren't the guys out there and I'm sure rotable costs are increasing all the time as well
