1 during the training period is not expected any time off to get home?
Expect to be in Japan for six months straight until your sim check rides with the JCAB, after that you will get some time off before the start of your OJT....!
What most guys do is that they have their family with them in their apartments for a period of time, just be mindful and DO NOT overstay the 90 days of the visa.....!
2 767 will be still in ops for long or they have plans for newer type?
When ANA finally parks the last 787 in the dessert to be turned into (whatever they make out off recycled carbon fiber) they will bring the crew back to Japan in a 76
If your desire is to fly something else, be it a 787 or anything else, I strongly recommend that you look elsewhere......!
