I would not suggest for booking the ticket, It can help definitely as a supporting document but can loss your big amount of money. Rest on you if you want you can book the ticket.AK84 said:Yes, you can and apply for her SOWP online in few days and she will get till Feb,2017 , Also booked her return ticket as well in case if they ask.
In my case I have asked travel agent to make a dummy ticket and I sent that with telling the truth to CIC that I have plan on this date and I am getting this ticket if you can consider this I would really appreciate.
