I guess I haven't been paying attention or something... but I recently noticed that Choice points can be converted to airline miles, minimum of 5,000 points for 1,000 miles. Not the best conversion rate, but nice to know for 'emergency' topping off of mileage accounts if/when necessary. In fact, not so long ago, I ended up buying an airline ticket because some airline bonus miles didn't come through soon enough... Would have been been worth saving 100s for the sacrifice of 5,000 points!!
