I only state my opinion and recounted a conversation between myself and a flight attendant . I thought I made that clear and had, nor have, any intent to mislead anyone. There is obviously a situation with these service animals that ought to be reconciled, and that is my opinion as a traveling consumer. The question of the original poster was his search for extra space by purchasing extra space and I was speculating , based on what I see and what the attendant told me, that his best efforts could, and hopefully won't, be hindered by one of the unexpected things that do occur on aircraft, whether the proliferation of these larger and larger service animals, or rebalancing of the aircraft. Ever been in the premium seats and the attendant takes someone from the back and says they need to sit in a row that you paid extra to be in in order to " rebalance the aircraft" ?
