why should you have to if you took care of it by selecting and possibly paying for an appropriate seat. If I have an issue with needed to use the restroom frequently and urgently, I don't want to have to discuss that in public with a stranger. I may choose instead to book and aisle seat near the restroom.Again, document it with the reservations and flight attendants if it's a quantifiable, qualifiable need and all of this he said she said me me me me me meeeeeeeee I'm better than you I need more than you I'm more important than you I'm taller than you simply...ends.
Could you imagine the line to get on a plane if everyone had to explain why they chose their seat. Why should they have to justify it. People with kids are no more or less special than others. If you want to choose a seat next to your child book and airline that allows that and check it periodically. that's what we do and that is what we will continue to do. Everyone has different needs.
