yes, for all our benefits can you possibly explain what the difference between cat4 and cat5 pay is? And before you say "time in seat", realize that you have failed to define HOW MUCH TIME IN SEAT is required to make cat5. Hope to never fly with you, seeing as how you cannot hanlde the stress of someone asking a simple question. I can;t imagine how it must be to fly with you if something really bad happens, like a maint. delay, or even a real scary diversion.
