I was surprised that so many of the people who would pay more for child-free flights were parents with young children themselves. I think it's unlikely that too many airlines will introduce child-free flights, because there's too much for them to lose in terms of people who would pay to fly but couldn't if they had children.
We've already seen some airlines introduce child-free zones, but a screaming baby's cry can carry quite far, so if that's the issue most people have with kids onboard then I don't know how successful they will be.
As many of 48% of parents with children aged 10 or under admitted they probably did not do their best to prevent their children being disruptive on flights, according to a survey.
The main reason for their not being more strict with offspring was that they were "on holiday" so were more likely to let their children do what they liked, the poll by travel agent sunshine.co.uk found.
