I travel long distance - Muscat to England return journey and am in my mid sixties so don't have the stamina I once had. I always try to travel KLM. I find the ground staff and cabin attendants to be highly efficient, helpful and friendly. Flights are usually on time and yesterday's touch down in Muscat was early (May 13th flight KLM421). I particularly like Schiphol Airport...clean, efficient and easy to navigate. 10 out of 10 KLM from this experienced traveler.
