I recently booked ATA for our trip to WDW in December. This is our first time flying with an infant. I booked online and did not find anything anywhere about infants so I booked our 11-month-old granddaughter as a child to make sure that she would have a seat for her carseat. I later read that infants fly at a discount so I called ATA and sure enough, the infant fare was $67 cheaper. In order to get the infant rate, I had to pay a $50 ticket change fee so ended up with only a $17 credit. I tried to have the fee waived, explaining that there was no mention anywhere of infant fares on the website and no way to book infants but got nowhere. I also tried to get a credit as the fare dropped $15 from when I booked it last week. I would have had to pay the $50 fee for each of the five tickets! I guess next time I will be checking out Southwest!!!!!
