I have never flown on Korean airlines before but used up the 120k Delta miles. I am booked on an awards travel for YVR-LAX, LAX-ICN and ICN-KTM. There are 2 non stop flights from ICN-KTM per week . Do I need to be concern that the flight may be cancelled as it is only twice per week? Is KE reliable? This will be in travel during April so the weather should be fine.
