Special Offer for British Airway Avios

Usually you require 250 American Express Membership Rewards for every 200 British Airway Avios. Now though October 10, 2016, you can have 300 British Airway Avios for every 250 American Express Membership Rewards. i.e. 50% more Avios.

I use a lot of Avios for short haul travel because British Airway usually cost less for short haul travel.
