• Additional cardmembers to the main Credit Card account are not eligible to receive a voucher. Any amount spent on any supplementary Credit Card(s) of the main Credit Card account will count towards the main account holder’s Spend Target.
• To be entitled to receive a voucher, the Member must have reached the required Spend Target within a 12 month period starting each year on January 1 and ending on December 31 (the “Twelve Month Period”) For the avoidance of doubt, if a customer opens a Credit Card account on any date following January 1 then they must have reached their Spend Target by December 31 of that year to be awarded a voucher.
• The qualifying Spend Target of the BA/Chase Credit Card is 30,000 USD (the “Spend Target”). Qualifying spend does not include cash withdrawals, interest, balance transfers and fees.
• Only one voucher can be earned in any Twelve Month Period. If the Member reaches their Spend Target within the Twelve Month Period then further spend will not accumulate towards another voucher. Members can begin earning towards their next voucher at the beginning of the next Twelve Month Period.
• When the Member has reached the Spend Target an e-voucher (“Travel Together Ticket”) will automatically be added to their BA Executive Club account. Please allow 4-6 weeks for delivery. The e-voucher will be valid from the date on which it appears on the Member’s Executive Club account and will be valid for 24 months.

• The Travel Together Ticket (voucher) allows the main BA/Chase account holder, when making a return flight booking using Avios, to book another seat on the exact same journey for a companion without having to pay the Avios flight price for that Companion.

I highlighted the important parts. Basically you have to redeem it on a round trip from the US only which nearly all flights go through London LHR with a few exceptions for Open Skies and London City service. So not only do you have high airport fees and taxes but you have to pay the super high BA fuel surcharges (YQ) so that free ticket will cost arouind $1,000 in many cases. I’ve spent a lot of time researching and the experts seems to agree there is no way to fuel dump this. The closest I can find is that it is cheaper to book two one way awards in and out of LHR but that doesn’t work with the “together ticket” as it must be round trip originating and ending in the US. .

I love my BA Avios card and many of the benefits but this is my least favorite feature.

By the way I do not earn any commission from credit cards on this site so this is just opinion and based on personal experience.
