RTW routing
Hello SkyTeam people. I'm a *A guy but helping a friend with some RTW routing. Could you tell me if this is a permissible itin?
IAH-CDG-DXB-FCO-ATH-SVO-DEL-ICN-HKG-NRT-IAH.
The part I'm concerned about is backtracking a bit from Dubai to Athens. Is this allowed? It is in *A but SkyTeam is far from my area of expertise. Thanks in advance.
