Hi!

I am trying to plan my honeymoon and looking to book business class award tickets, but am running into an issue that I'd like your assistance with as a noobie. I have enough Chase points to cover 2x business class saver awards on the way there (90k/person), however, on the way home I am ~15k points short but have AMEX points. Do you have any suggestions on how I can pool AMEX + Chase? Is the only option to buy 15k miles? Points balances below that can be put toward return flights. I've looked at Singapore which is a shared travel transfer partner but its 140k/person.

Chase: 165k
Amex: 80k

Thanks!
