Sounds like someone in the system wanted to say, I am sorry or thank you.
Perhaps they are trying to avoid CBC new articles.

My own personal example....
A few years ago, I checked in at YVR (was 35k at the time).
- Handed the agent my ID and aeroplan card.
- The aeroplan card fell off the counter between the belt and counter.
- Agent says, "Sorry - I need to call maintenance to get that out, just go to the maple leaf lounge and I will try to get your card extracted before your flight."
- Arrive at the lounge with my boarding pass and no card, agent say "Mr Fiordland", we were expected you, just go right upstairs.
- About half and hour later the agent that checked me in, finds me in the lounge hands me the card and say I am sorry again."
- Get to the gate, not a full flight. I board. The gate agent comes on the aircraft and says. "Mr Fiordland I would like to move you up to business class if you don't mind, just before closing the door." Same thing happened on the connecting flight.
