U.S. Department of Transportation (DOT) has required the airlines to disclose all inclusive fares on their websites targeted for the US audience already for a while.
Cathay Pacific had been showing prices excluding taxes, fees and fuel surcharges on its US websites for flights that doesn’t touch the US that is in violation of the DOT rule.
You can access the DOT’s page for the ruling here.
Here’s the DOT Ruling:
I would just hope that all the countries would required airlines to advertise and show on their websites only prices that are all inclusive. Personally, I prefer the way Brazil does it that has banned all the fuel/carrier surcharges.
