Wonderful|Jan 2026

Having required wheel chair assistance, I received amazing service from the ground and cabin staff. Everything was a breeze. Flight was comfortable but the entertainment system was quite dated. The chicken noodles served was amazing

Very Good|Jan 2026

Overall ok except crew not serve drinks with meal. Tried to push call button three times and wait for half hour but still no one response. Ended up with waving hands to some crew that finally walk passing me to get drink.
