DPS-Mataram or Jakarta-Mataram +taxi-fare to Kuta, Lombok?

Hi, what are the cheapest airfares I`m looking at, coming from DPS.. 300.000 + tax??

Is it possible to get a reasonable fare on a weekday, one day ahead at Jakarta airport?

My best bet is Trigana? Does anyone know their daily schedule? Otherwise any straight flight from Jakarta to Mataram..?

Also, how much is the taxi-fare from Mataram airport to Kuta and does it make a difference if there are more than one guests? Is there a coupon-counter at Mataram airport..?

Thanks a million!
