That happened with us in EK. (Back when they liked Qantas members) But on same PNR. MrP was SG and I was silver. We were in J. He got an upgrade to F at check in. I didn't. I was simply excited for him and told him to grab all the goodies. He asked if he could change it so I had it. She couldn't change it. As I went to board my boarding pass triggered an alarm. They ended up upgrading me too.
Hoping this Qantas love sticks in 3 weeks to Hawaii. Two P travelling in Y+ and points upgrade to J. Currently showing J9. Happy to use points.
MrP got a free upgrade Adelaide to Melbourne a few weeks ago. Pleased with that as it was a dinner one and didn't have to scrounge for food on arrival. I had made him a peanut butter sandwhich which he kept and offered it to an exec the next day who hadn't had a chance to get breakfast.
