Harness Seat

Any EZ jet with a 2-3 year old I just read that we must have a safety seat or harness?

Has anyone flown by plane EZ with a small child, because now I read on their website that needed a car seat for him to sit or flight safety harness, which is very expensive ... want to avoid the cost and inconvenience, if possible and have not had to do this on any airline before ?????

Any child over of 2 has to give his own seat on an airplane. This is the rule for all airlines. Under that can sit in your lap. Since yours is 2, you will to buy a seat and a seat will give you a little protection.
