Same day standby for A+ listers has been nearly useless for those of us traveling with a companion since the walkup fares for the companion are always expensive.

Will the new WGA+ fare bucket allow a same day confirmed change with an attached companion reservation -- all in one easy operation on a mobile device?

Or, will this require the WGA+ passenger to:
(1) check to be sure there are 2 or more seats available on the target flight,
(2) cancel the companion reservation,
(3) make the change to the WGA+ reservation
(4) add the companion back to the new reservation

I'm hoping the process has been streamlined.
