Kelly is a numbers guy, to suggest he is "in over his head" is simply not looking at the big picture. SWA has prospered in large part due to the single fleet type. The expense of keeping the 717's until the leases ran out outweighed the cost of getting rid of them quickly. Training pilots, mechanics and F.A.'s on two fleets, carrying spare parts for two fleets, and less revenue from a smaller aircraft in the same mission that a 737 already accomplishes in virtually every market does not make economic sense in the long term. If you think anything other than a serious cost benefit analysis led to the sale of the 717 you don't understand how Kelly operates. SWA will simply slow down retirements of the classic fleet to keep the fleet numbers flat while greatly increasing capacity.
