I am £700 short of 2-for-1 voucher this year. I think I will keep it that way for the time being because as soon as you reach your threshold, the 1 year validity will start straight away. The last date to use my card before the offer expires is at the end of October 2014. The thing is, most of the award availability on BA to places like Tokyo, Hong Kong, Singapore or Sao Paulo will be fully booked before and just after new year. So, if I hold it off and not spending $700 on my card for a few months, maybe I have a better chance booking a 2-for-1 award not so close to new year. Hmm…what do you think?
