If you have an Amex check your offers today, you might have one for $30 off $150. I had one on my Amex Blue. Could work to a few $$ of savings if you haven’t already bought tickets.
Verified this is currently available on Costco membership Amex cards as well.
It is also available for SPG Amex Cards. Have not yet been able to verify it’s available for my Jet Blue Amex though.
Also got it on my Platinum AmEx
