The bankruptcy of various Airbus client airlines, says Boeing, has not helped, leading to 90 A320 aircraft being parked, redundant. Boeing claims A320 lease rates have dived by more than 30% to less than $200,000 (£110,000) a month for a new one, and $120,000 for a recently produced, used jet. In contrast it says its 737s are retaining their value, being leased for nearer $300,000 a month.
