Hello Washington, prepare yourself!!
These comments, though negative and critical, are meant to give you as realistic a picture of AJX as possible.
As far as money goes, I would say that AJX is a low paying opportunity. It may seem to be OK now, but the provision for annual inflation adjustments is laughable, based on around 1% p.a. Probably only Japan has that inflation rate now. If you live in the US, you will be spared the further reduction of your salary due to the weakening US$. Don't expect any REAL action from AJX about this. It's been happening for a long time and they've just sat on their hands saying it's not their problem.
The hotel accomodation allowance is based on 10 nights in NRT, at US$50 per night. In reality the cost is up to $65/ night and you could expect to pay for around 8 days per month on average.
Per diem alowance does not cover costs of food and other living allowances, let alone the odd beer!
The roster used to be reasonably well balanced but with the introduction of new duties and the probability of more back of the clock stuff, combined with the shortage of pilots here, you can expect to be exposed to real fatigue issues and expect long term chronic fatigue to be a factor.
