Having been upgraded to Business class on my flight back to the UK two weeks ago, I felt that my years of flying back and forth from China to the UK were at last being rewarded with some perks. This made yesterdays events even more satisfactory – I arrived at the airport where they told me that since they were overbooked, if I would fly tomorrow, they would give me a free flight  and a 650 quid BA voucher or 350 pounds in cash. At firest I dismissed it but suddenly began to think that it might be worth doing – it was not absolutely vital that I arrived back in Beijing today  anyway. Also, the money meant a free return flight home at a future date. It really seemed too good to be true so i took them up on it. The only downside was that I then had to get home again having been dropped at the airport.
