First I'd like to mention that I take the plane every week between Halim and Yogyakarta for work usually using Citilink and it goes well. This time, due to no availability on usual flights I used Batik air. Here is my experience with them : I am a very displeased client.We are currently waiting in Halim airport, no information is being given to us eventhough our flight is delayed. We are being badly treated by batik air ground crew, they are mocking us. No one speaks enough English to explain to us that there is 2 and half hours of delay. We had to ask another kind passenger to translate for us. The announcements of updates for delay are not given in English and they are being disrespectfull.This is unacceptable from an air line like Batik air. I expected better customer service.Moreover, they are claiming that we cannot be compensated. I don't think that Halim International Airport should be called "international" when no one out of 6 ground staff can explain a simple delay in English.... unacceptable from such an airline.
