It seems like the base fare for a DONE4/AONE4 ex-Japan has gone down by about 4.7%. I guess that is an enhancement.
However, the fares ex-India seem to have gone up. AONE3/4 is up by 12.99%, DONE3/4 is up by 12.00%.
Fares ex-South Korea haven't changed.
I was only paying attention to xONE3/4 from these countries.
Probably, not 4.7% down, it is 5.0% increase.
On 20 September 2007,
Only DONE4/AONE4/DONE5/AONE5 ex-JPN fares were increased at 5.0%.
