Travelport 360 Fares follows ATPCO data application for CAR/Tour codes. Check that you have the correct format selected for your required code
in the Type (byte 105) in Category 35
A common mistake is to select CAR/Value in the Type box as shown in the filing below.
When Car/Value is selected the Tour Box text is expecting two sets of data separated by a / (eg Car/Value)
The above example shows incorrect coding that would result in being unable to price the fare because the Tour box text is one word.
To solve here you could either change the Type box to Tour/Other or add more data separated by a / If carcode is filed, it would never appear on the e-ticket. To have the tourcode issued on eticket, it should be filed as TOUR/OTHER (and not CarCode).
Below is the ATPCO data application showing the options.
