I’m a senior and have no idea how to get the best use of my Delta frequent flyer miles for my husband and I to go on our Dream trip from Atlanta to Australia and return from Auckland to Atlanta.

We have to arrive in Sydney on January 13, 2023 (some depart on the 11th) and return on January 31, 2023 from Auckland, New Zealand.

I have 311,643 miles and my husband has 118,638 miles. All on delta.

We would like to fly business class (Delta One) for at least the longest part of the travel due to our age and my husbands bad back.

Please help me!!
