Arabic show not that much I didn’t use my screen in 4 flights from Saudi Arabia to the United States.. and Back Also The New release movies there is no Arabic subtitles which is sad Any thing else was perfect

2.0

Poor|Apr 2023

The plane was very hot. We asked several times to make it cooler, nothing changed. VERY uncomfortable flight. Food gave me indigestion. Seats were so tight, could not even use the tray in front of me when the seat in front of me was reclined. Seats way too tight for a longer flight.

Poor|Mar 2022

I have a dislocated shoulder and in a sling.. . Little to no help. Headphone jack didn't work no on-board entertainment for me. Missed the evening meal, no one was proactive in helping me get it so gave up. Rubbish not being collected. Very poor, back to Virgin for me

Poor|Aug 2021

Long lines, chaos and incompetence during check in

1.9

Poor|Oct 2021

Delayed flight, no information as to why, more standing on the runway with no information and after landing, more delays with security gates not working. Just a shambles, lack of communication and lack of customer care.
