They no longer offer ‘two for one’ instead they offer discounts on premium cabin tickets from one to eight passengers. You have to price and book by phone. Early results appear highly promising."
Key details:
No longer limited to refundable fares, you can get a discount off of lower-priced premium cabin fares now too.
Applies to first class, business class, and premium economy now
$39 per ticket service fee (waived for Centurion cardholders)
“Travel must originate in and return to U.S. gateway (may exclude certain overseas territories) and select Canadian gateways” although one-way travel is permitted on some airline partners.
You can use Membership Rewards ‘Pay With Points’ to cover ticket cost
