* All flights in the month in which status is upgraded normally get the bonus
And if they are blue with very few miles, join Diamond club again (using a different address) and get another 4500 miles each and possibly blue+ card* for a free G&T on the Teesside to Heathrow and back
* will check the current in air promo on Friday, web site is only miles atm
