From my calculations, I think the 2 73Gs are included in the fleet plan in the 4th quarter since the fleet numbers add up with 2 new units. There have been 26 deliveries in 2014 so far. According to the new fleet plan, there would need to be 3 more 837/838/839 to equal the 29 new aircraft. So, we're either getting a total of 29 739s in 2014 or 27 plus 2 73Gs.
In either case, the new aircraft can add lift and/or continue to allow aggressive mod work for WiFi installs and slimline seating. There are currently more than 13 73NGs in maint/mod of which 11 are probably getting WiFi. and possibly scimitar winglets.
