Here is what happened to my wife and I last August coming back from New York to Melbourne. We had booked and PAID for Business seats and had confirmed and booked our respective allocated seats 12 hours before leaving New York.
Arrived at the airport, checked in and were given Boarding Passes, DID NOT CHECK THEM... as we knew our seats, so we thought. Got on the plane and found my wife and I were separated, initially taken aback and then looked at Boarding passes with different seat numbers.
My wife was sitting next to a young guy who had the window seat and I was sitting elsewhere in Business. Kicked myself for not checking and mentally noted....NEVER DO THAT AGAIN..ALWAYS CHECK TICKET BEFORE LEAVING CHECK-IN.
Sipping on a glass of champagne and CSM spoke to me and said she had noted we were on the same booking and why were we sitting apart, jokingly said "are'nt you speaking ?" told her that we had pre-confirmed seats together but boarding passes had been issed at the desk and it was my fault anyway and I had not chedcked them etc"
Next thing the CSM goes over to young guy and asks him to go into the galley with her, they come out and she advised me he had "offered" to change seats with me ( I was elsewhere in an aisle seat), my wife said she clearly got the message he was staff.
True story..about 5 minutes later the Captain "happened" to come into the section and asked us if all was fine, enjoying the service etc,etc, we told him we were, we had a chat and off he went. Now that IS customer service.
Obviousl the staff member knew ther person at the desk in New York and wanteed a window seat and mine was it even though it split my wife and I up. Was I angry,well initially annoyed but I should have checked the Boarding Pass and did not so you can't always blame other people. It was a good lesson for me. I always double check now that the seat I book is the seat I get. My philosophy is always..First time is the lesson, 2nd time is the mistake.
Both the CSM and the Captain could not have been better and both did it unprompted. I did wonder though what might have been said to the staff member by the captain.
By the way my son is a Qantas pilot and we could also have gone staff travel ( maybe if available, but maybe not) but we had paid full price for our tickets and there was no way that the CSM would have even known that. My status then was Platinum so I guess she was just doing her job...exceedingly well and looking after her customers.
