The selection is indeed rather useless for SEN/HON, or even those that frequently fly business. I'm quite sure they could come up with things that will not cost them a fortune but are still useful. For example a First Class lounge access voucher (even useful for a HON to bring in someone on a different flight that day). Or a Wifi Voucher for long distance flights (also this useful for HON as they will not get free Wifi if there is no F).
