According to S7 Airlines the 10 Boeing 737-800 will be for a new entity S7 Charter Airlines.
Wikipeida claims: This division will concentrate of flying tourist passengers to holiday desinations. Initially, the aircraft for this division will be used from within the mainstream fleet, but during 2010-2014, 10 Boeing 737-800 aircraft will be leased with an all economy layout
The 29 Airbus 320 will mainly be for scheduled service to fly around Europe and Domestic. Plus, S7 Air currently operates 7 A319- I believe these planes were purchased from NWA.
What is the point on seperating the orders?
Is it better to configure 737 in Economy only?
Or maybe when they ordering the 15 787 they asked Boeing to build them 10 737 exactly to the same specs as RyanAir? lol
