13 out of 18 people on today's flight were upgraded and the front cabin was not full. If you check the PDA site (

If you are not an elite but you are on your father's PNR you may want to have him call the Elite line and split the PNR. This gives him a better chance of being upgraded. When he gets to the airport, have him add you as a companion to the upgrade standby list.
