According to a press release on Ryanair's website they exercised 9 more options yesterday for delivery in 2007 (3 Sept, 2 Oct and 4 Nov). In the same timeframe they plan to sell 5 737-800s delivered in 1999.
By their reckoning they currently have 83 738s and 9 732s.This change means that there are 156 more firm orders to be delivered (by 2012), minus the 5 mentioned above, plus 179 options remaining for 2008-2014.
Selling the first 5 738s is an interesting move - financial jiggery pokery, forced because early 738s can't be retrofitted with winglets (I believe Transavia are replacing their first 2 738s for the same reason), or evergreening as they claim?
