Looking to book one-way flight to Shanghai next June for 4 passengers.

Both airline offer a business class so I was wondering which is better or highly recommended over another.

Delta:
80k one way with one layover in Seattle(2hours) - 80k Delta

Eva Air:
80k one way to TPE, pay 8k for flight to Shanghai (Economy) - United


This will be the our first time flying business.

Flying out of LAX. I see flights available for 4 passengers at the current moment. I understand things may change and availability will fluctuate within time.

What would be your preference?

Thanks!
