I assume you are talking about 50% of the full coach price? I can see where that might be of value at times, but generally when travelling with a child, the trip is planned well in advance (not a last minute business trip). It appears that if the discount seat price is less than 50% of the full coach price, then they just sell you one of those. Is that correct, or is there a way to get a ticket that is 50% of the discount price?
