Aircraft leasing takes away the initial high asset cost of purchasing an aircraft, allowing funds to be available for business development rather than being tied up in capital expenditure. This gives airlines the flexibility to expand (or reduce) their fleet in reaction to local or global markets at relatively short notice. In short, leasing provides a solution to get your aircraft into revenue service thereby maximising profits whilst keeping capital costs down. Shorter term lease arrangements in particular also provide the opportunity to set up and evaluate new routes or take on specific contracts. Wet lease arrangements can be the solution to cover aircraft downtime due to maintenance or other operational issues that would otherwise leave an airline temporarily short of capacity. There are essentially two types of Lease; Wet Lease and Dry Lease..
