So l flew from Atlanta Ga to San Antonio,had my two boys 3 years and 18 months,an hour after we took off one of the hostess asked me if l had paid for my son to sit on that seat,and i did not get it how l was going to get in a plane with two kids and not pay for the seat and my son is 3 years,l found it very disturbing and it was an hour after taking off,,i was sad and embarrassed and disappointed about this approach..
