Hi,
Many have said JAL only requires First and Last name on ticket, when my passport has FIRST MIDDLE LAST name.
But I just called JAL reservation at LAX and agent told me from her 20yrs experience, it is 50-50 from US to japan. And it even has higher chance reject boarding when fly from JAPAN to TAIWAN. Also will japan immigration reject me entering japan after flying 16 hours from lax-kix?

Has anyone had experience recently within the past year or so? All the posts are back in 2014 or like over 4yrs ago. With Covid, all countries might have taken more pre-cautions esp. Japan had required Visa for US citizens few months ago. Just lifted it this October. Any advice or share experience are highly appreciated.
