There was a period, about a year back, when transfers to BBk, even though 'long stay in Thailand' was selected, was shown as a local transfer.
IME, that was the only period, since that specific purpose was introduced by Wise, that FTT was not shown by BBk. Wise do advise that such a designation is not guaranteed but it has, in the main, been consistently applied. So, it does make a difference, until it doesn't..........
