delta.com "infant in arms" add option

[flyingBlue]

on my itinerary on delta.com there is an option at the special service requests there is an option  "infant in arms", it lets me add an infant on my itinerary, does this mean I can add an infant for free?! screenshot attached.

What ended up happening? Anybody know how this works? I have the same issue. When booking an extremely cheap Fair to BCN I forgot to add my child and figured Id call and add him later at 10% of my ticket ($400). Upon calling they wanted close to 200% for my kid so I just added him to the itinerary. Called delta and they said it seems to be confirmed. Praying it works.

It only adds them to the reservation. Does not add a ticket. You will need to pay for the ticket either over the phone or at the airport
