Sorry to disappoint you all, but the traveling public will fly with the airline that provides the cheapest ticket to the destination of their choice at the time of their choosing. If this happens to be KA, fine. If it happens to be CX, also fine. The answer to the question posed at the start of this thread is subjective. If safety is an issue with said traveler, then both airlines satisfy the requirement. Hope this helps you in your mischievous quest.
