Sorry the review I just posted was for this flight which was the long haul flight. The planes were nice and that’s about it. No 2 full service meals, only a little tiny vegetable wrap an hour into the flight. Nothing else until the last 2 hours which was the only meal served. Terrible at that. Also no amenity kits were given. Not even a toothbrush. No snacks or nuts in between. Just an awful experience with a mediocre crew. Very disappointed in this supposed 5 star airline according to Skytrax.
