That won't be fixed anytime soon as its not possible even direct with EI to assign a seat with 72 hours over the phone (Not 100% true there is a way but it will not show as assigned and most agents have no clue how to do this and can be undone by the passenger, but every flight I travel on out of Dublin has this set and I made it work out of SEA once)

That is an all Y flight so its not illogical
