Scoot Airlines are introducing no cry zones.
You pay an extra £10 to sit away from all children under twelve.
As a parent with a young toddler I would not only utilise this when flying without my DD, but would also feel more relaxed when flying with her knowing those in my cabin most likely opted out of the 'no cry zone' so won't mind if my DD makes a little noise now and again.
I wouldn't allow my DD to disturb people usually when travelling, just think this would allow me to feel a little less tense about her making noise where I can't prevent it or it takes a little longer to soothe her etc...
