It appears that the European Commission may be withdrawing (or already has) IATA's immunity to prosecution for operating as a cartel.
What does this mean?
IATA has already agreed to remove sales indicator codes from travel agents global distribution systems. These codes such as (SITI, SOTO, SOTI) set rules for fare construction and vary from country to country.
Hence, RTW's will be able to be ticketed anywhere at the local published fare since there will be no difference if you are an agent in Egypt, Bangkok or the USA.
It will be interesting to see if all RTW's are all going to be common rated. Hope not!
