Tika. Quite a few airlines are not on the web sites like Seat Guru and others so that is not surprising. However, I do believe that they have a seating map on their own website so you can seat the seating arrangements. It is two on each side and then four (I think) in the middle. You need to do your seat assignments by the old fashioned way, phone Air Tahiti directly. Then you should have no problem getting your seat assignments. At times Regent will just have a "block" of seats with no names on the manifest. If they tell you that you are not on the plane this is the reason why, just wait a few weeks and call back.
