Currently over 20 aircraft grounded, with over 40 new deliveries due before next July (Down as far as Boeing c/n 37539). All being purchased. NO lease opt outs.
Cash reserves well below your figure - approx 1.4bn
As for disposal - talk to ILFC or any other lessor. Market is awash with 737s, as the majority of airlines that have gone under recently were 737 operators.
On the other hand, most other airlines have structured fleets with a balance of ownership and leasing, allowing the airlines downsize if required without retaining excessive capital costs. (No wonder that ILFC is in deep problems - it is a subsidiary of AIG). Not so FR.
As for FR Longhaul - this story started 18 months ago when MOL tried to defer 737 deliveries. Havign screwed Boeing to the wall for compensation in the past for delays in deliveries, Boeing have been unwilling to defer deliveries to him without severe penalty. MOL tried to convert some 737 orders and options to B777 (more easily leased onwards/sold) - but Boeing were not biting. And neither are Airbus.
