HCMC - Da Nang then Da Nang - Ha Noi a week later. Passengers wandered around the cabin changing seats as the plane taxied to the runway and walked in front of the engine on the tarmac as there was no roped off area under the wings talking on their mobile phones. Safety demonstrations could not be heard in English due to the heavy accent and muffled PA. When the captain asked the cabin crew to 'prepare the cabin for landing' they simply dropped what they were doing and sat down. The second the plane landed passengers were up and opening overhead lockers despite the plane still hurtling down the runway. The fares are very cheap and most flights are barely an hour so its a great choice for these short domestic hops. Warning - Da Nang airport is not the type of airport you would wish to be delayed in - it has the atmosphere of an immigration detention centre.
