Wonderful|Aug 2025

Overall journey was good. The economy seats on this airbus a350 was the worst . Too narrow and no underthigh support . My next journey from Hongkong to kathmandu was better as the economy seats on airbus a330 was a lot better than on this plane . Cathy should make a note on this . The long haul flights should have at least comfy seats compared to short flights from Hongkong to ktm
