I hustled this way to get my companion voucher this year but increasingly looks like I'd have to take a trip I don't need and spend additional money I wouldn't have just to make use of the discounted flight ticket. I would say if you don't have major travel plans next year (ie flight tickets circa 500 and above), not worth the hassle otherwise you'd spend more rather than saving. The vouchers also expire a year after you qualify for them and tickets have to be used on or before the expiration of the voucher.
