A few friends have just returned home from university for the holiday on KU102/411, 772 and 343. They found KU to be surprisingly good, comparable to Emirates. You can expect to find the usual gadgets available in other world class airlines, PTV, footrest and so on. All flights were on time and the food was great.
To them, the only downside to KU was the 4 hours of transit time in KWI before catching the next flight to BKK - and after a 7 hour flight I doubt one would be in the mood for shopping.
KU had local cabin crew onboard flights departing BKK when they were still codesharing with PR on BKK-MNL route. Not sure if they still do - but that's always a nice touch.
Being a Muslim carrier, any idea if KU's also a 'dry' airline like Royal Brunei?
With the current situation in the Middle East, Middle Eastern airlines in BKK (I'd expect the same elsewhere) are now slashing prices to Europe - including KU so you can probably expect to see full flights to Europe from Asia packed with students in the beginning of next year.
