I got a call back from the helpful girl at MBNA today who said she had spoke to the "Points" department and they need the
Date, names & flight details of all bookings involved????

I said that the statement lists the booking reference. That should be enough. It's not her fault, she is just passing on the info from another team who I feel don't have a clue.

Is it worth a couple of thousands miles to give them details I feel are irrelevant? I think not....

MBNA and BMI need to sort themselves out.
