A dry lease is primarily an aircraft rental
The lessee places the aircraft on its own operating certificate where permitted, supplies crews and handles maintenance, insurance and day-to-day operations.
A wet lease includes the operating platform
The supplier provides aircraft, crew, maintenance and insurance, so the customer can add flights without integrating the aircraft fully into its own fleet.
Contract lengths tend to differ
Dry leases are commonly used for multi-year fleet financing, while wet leases can be short-term or seasonal, though long arrangements also exist.
Regulatory treatment is different
Authorities examine who has operational control, whose certificate applies and whether foreign wet leasing is permitted under local rules.
Economics depend on the problem being solved
A dry lease can be cheaper for long-term use if the airline already has crews and infrastructure. A wet lease is valuable when capacity is needed quickly.
The terminology matters in disruptions
Passengers may see another operator named on the booking because a wet-lease provider is actually flying the service, even though the marketing airline sold the ticket.
A dry lease provides the aircraft without operating services
The lessee supplies crew, maintenance and insurance and operates the aircraft under its own certificate.
A wet lease includes aircraft and operating capability
The provider supplies the aircraft, crew, maintenance and insurance, allowing the customer to add capacity without fully integrating the aircraft.
Control of the operation is the key distinction
Who dispatches, crews and legally operates the flight matters more than the paint scheme or marketing airline.
Dry leases suit longer-term fleet integration
An airline may take an aircraft for years and treat it almost like an owned fleet member, including its own cabin standards and procedures.
Wet leases suit speed and flexibility
They can cover short peaks, aircraft groundings or delivery delays without waiting for pilot training and regulatory approvals for a new type.
Regulators scrutinize cross-border arrangements
Authorities may limit or approve wet leasing differently from dry leasing because operational responsibility and labor implications change.
