I have collected 82,000 Avios, but it seems that unless one is a member of BA's Frequent Flyer club there is little point. I tried to book a return flight to Philadelphia and was quoted 40,000 Avios. Fine. However, I fully expected to have to pay additional taxes etc. but was certainly not expecting these to amount to £359 - plus my 40,000 Avios! Surely this total is equivalent to a conventional (i.e. non-Avios) flight! Am deeply disappointed and feel disillusioned about the whole scheme. Would have readily traded in more Avios to cover the flight cost but there was not an option for this. I shall be interested to hear other people's experiences/observations re the usefulnesss of Avios.
