I am trying to book a flight for my wife and 2 kids from my home country to the country where I currently reside. My oldest kid is 19 months and the other one is 8 months. I tried booking to our preferred airline and since the airline only allows 1 infant per 1 adult, I booked 1 adult, 1 infant and 1 child.
The airline specifically says in their website that:
"Two infants with one adult: If second infant is over 12 months and able to sit on a seat with a seat belt; Second infant shall travel having paid Child fare".
However, when I try to book online, I couldn't continue with the booking since an error says that my child must be at least 2 yrs old to be book with a child ticket. I tried booking thru customer service but they keep insisting that it would be difficult to travel with 2 infants, even if I told them that my eldest child can already sit and walk. And also, my wife will be flying on the same flight with her friend whom we have asked to sit beside my family and help my wife with the kids while in the airport and on the plane. However, her friend already has a ticket.
My question is, would it be too risky to put in wrong birthday for my oldest child (make the website think she's 2 yrs old+) and continue with the booking?
How often do airlines check the passenger's birthday if it matches the one in his/her passport? Would a wrong birthday be enough reason for offloading?
