It is dreadful.

Points regularly fail to post. As you say, the retailers often say they haven't got 'the machine', or it's not working. Of course, BAA say all you have to do is send in your receipts for credit. Two problems: 1 - the points are often worth less than the postage, so why bother?; 2 - why should we do their work for them without recompense?

The coup de grace is using BAA's website to book services such as car parking. You'd think you'd be certain to get the points, right? WRONG! I'm still waiting for credit for such transactions going back 4 months.

Also, the points expire after an absurdly short time.

The scheme could be useful if it delivered, but it doesn't.

Oh, if you ever get the points credited, they can be exchanged for a number of items including miles with VS, CO and BD.
