I have another experience update:
Last week I used my High Miles card to get a free personal pie and lemonade from Pizza Hut. It was pretty simple: a short form to fill out on the CAL website and the confirmation was received within seconds to my inbox.
I told the cashier that I wanted to use the benefit and she didn't even need to see the confirmation, only the actual card. The receipt had a grand total of 0 NIS: a charge of 42 NIS for the deal and then a second line with -42 NIS discount.
I personally enjoy the lounge (and thankfully had access through a different card), but I think some of you would beg to differ and would rather have a benefit like this :-)
