Avisheshjee,... safety-wise I could say this is one of the safest airlines in Asia as its B-757s have not encountered any major accidents in the past 20 years ! The only hitch is the unreliability of its schedules. Nevertheless, NAC endorses its passengers to other airlines as and when there is a deviation in its schedules. So, in my opnion it is worth giving a try if the fare is coming cheaper.

BON VOYAGE !
