So, your saying that you don't work at SWA, don't have a clue how they plan on training, and have zero idea of how many pilots they hire for training events? Not so fast Spooky...it appears you're opinion is exactly that.
Well TC you are an AF dooley I see, so I suspect you know squat about Part 121 training requirements, much less the 737-700 One thing you can make book on is that they will, just as all other airlines, do it the cheapest way possible, ergo they will combine it so as to maximize the effectiveness while keeping costs to a minimum.
Don't you have airplanes that need fuel. Run along now and fly safe.
