Assume you are blue card holder and clocked up 25K Tire miles back in January you will now be silver until 28/2/10, if you were already silver this year you would just be extending the expiry from 28/2/09 until 28/2/10.

If you get Silver this month then you should receive the benefits once you have completed the qualifying flight, and your silver privileges will be valid until 28th Feb 2010.

If you get another 25K before 31st December then you will be gold until 28th Feb 2010.
