buy your wife a ZED fare on the same flight as the one EK will book you
...and introduce her to one of the joys of EK staff travel from Day One... as she watches you and your flight taxi out on its way to (and/or from) Dubai... from the staff travel check in desk... which, unless you choos very carefuly, on 90% of EK flights, is about as far as she will get with a ZED, ID90 or any other kind of subload ticket.
