I heard that EVA Air will increase the number of miles required for business class awards on European and North American routes. It's supposed to start 2011.
Is it a good idea to cash in some of my miles for business class award from Europe and just change the dates later?(at the current lower mileage requirment) I assume that once the award ticket is issued, they won't ask me for more miles if my travels actually take place in mid-2011?
