Give me one destination worldwide from March and onwards and I will tell you how you can use BA miles to reduce the cost of the trip or upgrade.

What surprises me are the number of people expecting to have full availability in any cabin on any date and on a specific route. BA miles are not a carte blanche to any flight in any cabin. They are helpful if you plan and are flexible.

I have never had a problem using my miles to pay for reward tickets or MFU.
