How are our ACMI leasing services different?
Wet leasing or damp leasing, FLY4 tailor to your requirements.
When it comes to ACMI leasing solutions, FLY4 offers both wet leasing and damp leasing services.
Wet leasing. Ideal for airlines looking to maintain their own in-flight service.
With FLY4’s wet leasing solution you can rely on the all-in-one operational solution, with the utmost flexibility and short lead-times for your organisation. Our competitive Block Hour rates are typically based on an ACMIO logic excluding crew per diems, transport, hotac and any special requirements you may have. This service allows you to scale operations rapidly without the need for hiring or training additional staff, making it a flexible and cost-effective solution.

Damp leasing. Perfect for airlines with enough crew.
Often airline customers want to provide their own signature in-flight service utilising their own cabin crew. FLY4 can easily accommodate such requests and will work with you to complete the required Operator’s Conversion Course in the most efficient, timely and compliant manner.
This option is ideally suited for airlines seeking to deliver their own ‘In-Flight Services’ product by their own cabin crew, but are seeking to expand, enhance or complement their own in-house production.
