One reason I'll never visit Australia and NZ is that last I checked Business fares (2019 when I was going on a cruise out of Hawaii) it was extortion. I'm thinking it was $8K round trip total for mainland to Hawaii and then Hawaii to Australia. Could I do it and pay the bills? Yes, but it just doesn't seem to be a good use of my travel $$. And I will NOT fly that route in Coach.
I "blame" my late husband for getting me hooked on long-hauls in Business. He was a man of very modest tastes but over 6' tall with a creaky back, and 15 years older. I flew a lot on business and we used points to upgrade once on the way home from Scotland. After that it was hard to go to the back of the bus so we traveled to Europe a bit less often and I was a wizard at accumulating and using airline miles and we flew Business Class.
I made a half-dozen trips to India on business and the first time the Chief Actuary allowed anyone willing to fly Coach to stay overnight at company expense in London, Paris, Frankfort.. your choice. I chose London and it wasn't too bad. Business Class was better.
A coworker who later flew a nonstop from Toronto to Delhi in Coach because Business wasn't available said it was "brutal"- and he was short.
Nah, DS and DDIL are VERY frugal. DS says whatever I leave behind will go straight to the 3 kids.
When the youngest (currently 3) is a bit older I want to take the family to Costa Rica. They'll be in Business whether they like it or not.
