Adding a child to an existing ticket
 

QUESTION for EXPERTS !

Dumb me : I too quickly booked a GVA-BDS for me and 1 of my child. Now my second child is free to join us.
But the system dosn't allow me to add a person to an existing ticket. And when i try to make a new booking, the system (obviousely) dosn't allow you to book only 1 child.
Do I book an adult ticket for him (he is 4) and call it a day ? Would there be any issue at the airport?
Or do I try to call easyjet to try to fix thing (adding a child to my existing ticket / or changing my eventual new booking from adult to child) ?

Thanks to you all experts !

Contact them. They'll add the child to the existing reservation

and if you get cut off just keep calling back ... Easyjet staff tend to hang up if they get asked difficult questions !
