There were a couple of mishaps, but even with them their commitment to great service is noticed. The flight to US was delayd, but they provided a small voucher for food. Then the luggage didn't arrive because was rescheduled for the flight next day . Still, it was delivered 200 miles away within hours of the landing of the flight. I give them the highest evaluation because of their desire to make it right. BTW, the food was quite economical for a long haul flight - just a sandwich.
