M: Alexandra, did you work at an airport before? You said you worked in aviation.
W: Yes, my previous job was writing contracts for an aviation company. We bought and sold airplanes and aircraft engines, so we did a lot of marketing and leasing and communicating with people from different countries. And sometimes airlines wanted to buy equipment, so we had a lot of negotiations.
M: Can you explain what leasing is?
W: Leasing is when our company owns a piece of equipment, either an airplane or an engine, and a customer has a need. For example, if their airplane has to do some maintenance, and they need a replacement, then we will let them use our airplane for a certain number of months, like you rent a car.
M: Oh, wow! And you lease not only the planes but engines?
W: Sometimes you have an airplane that is delayed at the airport because of some reason and they need to swap an engine out, or whatever.
M: Right before the plane takes off, they sometimes switch the engine?
W: They’ll take the passengers off and put them on another plane because it takes a lot longer than the 10 or 15 minutes turnaround, but, you will have...it’s more than an emergency type of situation, so they’ll take the engine off, and it might be an overnight deal so we go ahead and furnish a replacement engine until they can move that plane back to where it belongs or have the engine repaired.
M: So can you lease a pilot?
W: Yes! You can lease a crew; it’s called a wet lease. And we used to do dry leases meaning we only provided the equipment but a wet lease includes a full crew that will fly the airplane, flight attendants, etc.
