Lessors have a preference for narrowbodies over widebodies due to more remarketing opportunities and the substantial reconfiguration time and cost a larger aircraft requires. Reconfiguring an Airbus A330-300 can cost $7 million and even more for a Boeing 777-300ER or an Airbus A380: introducing IFE - $1.5 million ($5,000 per seat), replacing business seats - $1.5 million ($30,000 each), replacing economy seats - $1 million ($5,000 each), a new lavatory or galley - $100,000, moving a monument - $35,000, class dividers - $50,000, passenger service units - $9,000 per passenger, sidewall panels - $6,000 each, updating the IFE database - $125,000, repainting the aircraft - $100,000, engineering costs - $100,000.[18]
