Just a quick explanation for above posts.
Our daughter, son in law and son were flying out to join us on holiday and were delighted to be upgraded on the Dubai to Kuala Lumpur flight.
We were flying home together, the three of them were in Y and hubby and I were in J.
When we boarded in Dubai from the lounge, three grinning faces were seated in Row 6 in front of us !!!!
Two Upgrades in four flights with no status is pretty good going !!!!!
