Can someone pls help me try to understand the formula for booking a lap baby. Their site says 10% of the base fare plus taxes. The tickets was 1208 plus taxes bringing it to 1447. 10 percent is either 120 or 140 depending on what they consider the base fare. Why am i being quoted $355 from multiple agents and supervisors? I asked her to explain the breakdown and she says the base fare is $290. When I asked her where she got that number, she said that is what the system is saying. Can anyone help me understand this? I need to book 2 lap infants and this will cost way more than it is supposed to. More than double. Is there any dept or agency that deals with this?
