The reason for this is that they have planned Havaist shuttles and IETT ( municipality buses ) at the same exact route. Ex: Halkalı, Mahmutbey and Mecidiyeköy lines
Also, the Arnavutköy and Göktürk/Kemerburgaz shuttles were aiming airport employees however, they prefer to use buses because of the monthly transportation card they are getting from their company.
For the Zekeriyaköy route, I would comment that there would be just a few people in that area using those buses as someone who could afford to live in a 1m+ plus house, could afford to pay a private transfer or a carpark.
