ACMI operations are very different from working for one operator. Flexibility and readiness to embrace change is something that you have to be prepared for. The two of us @TheRegionalPilot both fly for an ACMI operator.
For those of you not familiar with the acronym, ACMI stands for Aircraft Crew Maintenance Insurance. When an operator such as Norwegian, SAS etc. needs extra capacity for a shorter or a longer period, the ACMI operator steps in and offers the services required. The ACMI operator is capable of delivering a complete package and provide the needed capacity on established routes at short notice.
Our operations are based on demand so you never know what the future will bring. Right now, we are working for two main operators, but the ACMI operator we fly for also has a short-term contract for operations in the UK. To prepare for that, we had to study the procedures that are specific for operations over there. ACMI operations can thus be challenging and you have to be prepared to work in different environments and at different locations. This kind of operation is definitely not for everyone, but for those of us that thrive in a dynamic environment, it is the perfect job.
