Although it was their first international route (probably launched with DEL-KTM, I don't remember) it hasn't been doing well at all. It is kind of an oddball, relying heavily on O&D. There are 2 options moving ahead, I think:
1. Downgauge to ATRs (or CRJs with JetLite) and offer the same mid-day flights
2. Reschedule for BRU connections at MAA. The problem here is that this will require two flights to operate MAA-CMB which will ony make it worse. Maybe if they used 2 RON ATRs/CRJs for departures at MAA around 10pm and 4am, it might make sense.
