Sorry I have joined this debate a little late. I took pleasure in booking my family 1 + 12Mth baby + 6 Yr Old and 4 Yr old into business class on award tickets this summer.
I enjoyed the fact they would receive better service and a more stress free trip for all the pain of my FF mileage. I fail to see the problem, these are consumers, however junior, and if someone is paying for the luxury where is the problem?
Personally I enjoy kids on flights and I agree with all of the above references vis a vis snobbism etc. If the parents are trying that's good enough for me.
