Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

Flight crew was super friendly and helpful. Food was frequent and honestly pretty good. Plenty of on-board entertainment. Economy seats are super cramped for such a long flight, but the crew allowed people to get up and stretch, and kids could wander with their parents, so we all made it work. Overall a very good experience.

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

Outstanding service, great food, friendly & efficient crew, safe & comfortable flight

Staff were not attentive, wifi did not work, cut my head in the bathroom due to the position of the soap on the sink, had blood running down my face, told staff, they had no expression no sympathy, didn't even say "sorry", they said "oh we will have a look at that" about 10 mins later the purser brought me a bandaid, still no sorry.... Shocking

Starlink is great Crew was polite Business class didn’t get a welcome drink just water and snacks were ok
