From my travel experience I found that these airlines are so punctual and it departs and arrives at the right time.
I have travelled roundtrip from cochin airport to kuwait and it was a pleasant experience for me.The seating space was sufficient.The food availiability and hospitable services was also interesting. The airconditioning is moderate which is not too cold and not too low. Even the economy class was well furnished and comfy.The airhosteses are so kind and helpful whenever you need them.
