Food should be better and according to the passengers traveling from particular countries for eg if traveling from Dubai there should be halal Arabic food not everyone like pasta and western food. My kids and i stayed hungry whole time in flight from Toronto to London, London to Dubai, Dubai to London, and then London to Toronto

Amazing service for my daughter who broke her leg. Osab was waiting for us with a wheelchair and escorted us from the gate through baggage claim and to our express train. Amazing service!
