Bought NRT-PER a few years ago, no issues.
The only one to be wary of that I know of is ex-BKK ; if unable to present the C/C used to book to their office in Thailand within a few days, the ticket will be cancelled. The message is very clear when booking for this one, however.
There are a few more than just BKK:
