I booked Club World flights home from our Honeymoon almost 8 years ago as a surprise.

When we boarded the flight at Barbados, my wife lead the way and walked past her seat. When I pointed out the seat number on her boarding pass matched that on the seat, she insisted that "No they are not our seats, we are in the other row 8 back in economy". The look on her face was priceless when I explained that there was only 1 row 8 and we took our seats. I also like doing this kind of thing, she thinks we are traveling Club to HKG next March, she will be surprised to find she is traveling first.
