Thanks , but you are both missing the point, BA are not allowing the BMI number, you need to complete the booking and you will see the number is removed. I also when from initial person to the duty managers in both BMI and BA bookings and FF Clubs, EC and DC. BMI refers to BA and BA Says the club no longer exists. Lastly my membership number has eleven numbers with 5 zeros, but in the end does not matter when BA says BMI DC no longer exists. In the end may just cancel the flight with BMI.
