If not and I get a total of 2 in J with 1 in Y, I will obviously be the one sitting in Y.

Looks like there is R availability on 63 April 21.
If there is only one seat at the seven days window, upgrade your mother first.
As to a third person, it's against the rules. But it does not hurt to ask. If there were empty seats...
