MIA-BKK Business Class. SWISS via Zurich or JAL via Boston & Narita?
 

Myself, wife and six year old will be traveling from Miami To Bangkok in Business Class this summer. We have two of the folowing options:

Swiss to Zurich and having a 7-hour layover and then onto Bangkok.

Miami to Boston on American with a 3-hour layover, and then JAL to Narita with a 2-hour and twenty minute layover in Narita before departing to Bangkok.

Were very interested in which airlines offers the best soft product and accommodation for three.

Thank you in advance for your help.
