My wife and I bought an international flight from Delta Airline.

Then we found out later that my parents couldn't take care of the kids. I called up Delta airline to purchase 2 extra tickets for my 2 and half, and 4 yr old.

I was told by representative that Delta no longer sells child fair for international flight. All passengers over the age of 2 have to pay ADULT fare.

I usually travel with United and always get a child fare for my kids, I pretty sure that United still offers child fare which is like 75% of the adult fare.

Is this something new that airlines start charging full price for kids?
