yes that is true about the onload cat into yc....
not helpful when the only seats left are in jc or pc.
I have seen staff on 20 years service being left behind (no seats in YC) as their upgrade category was not as high as a "visitor" with one year!
If YC is full your LSL or Annual leave mean nothing. Someone who has a J15 or above will get in ahead of you into JC.
So if there is one seat left on the A/C and its in JC, a person with a higher upgrade who has been employed for one year gets it! than someone who is on a J17 20 years.
I called staff travel and they have confirmed this!
