Frequently Asked Questions

What does ACMI stand for?

Aircraft, Crew, Maintenance, and Insurance. An ACMI (wet) lease includes all four elements, so the lessee only needs to provide fuel, airport fees, and ground handling.

How do wet leases affect pilots?

Pilots employed by wet lease operators may fly under different airline brands depending on contracts. It can offer variety but may mean less stability than direct airline employment.

Why would an airline choose wet lease over hiring?

Speed and flexibility. Hiring and training pilots takes months; a wet lease can add capacity in days. It's ideal for seasonal peaks, aircraft delivery delays, or covering grounded fleet.
