Is infant air ticket free of charge? I'm bringing my 6-month old baby but when i checked the ticket price, she's being charged. Also, do i have to request for bassinet if i'm taking SQ? Is there additional charge for a bassinet? If there is no bassinet available, does it mean baby will be on my lap? Thanks!

Our baby is almost a year old and we decided to go on vacation, I thought for a long time where to buy tickets, in the end I found a company and there is a business class consolidator https://businessclassconsolidator.com/ and we took business class tickets so that we could fly comfortably with baby. Because it will be our first flight. I think everything will go smoothly.
