Pacific Airlines is not a new airline, but it is a good competitor for the national airline, Vietnam Airlines. The tickets are cheaper but the service is still quite good, with friendly staff full of helpful information and free pickup. These are some of the reasons that lots of people choose Pacific. They also occasionally have promotions for international flights or throughout Vietnam.
I hope the Vietnamese government allows more airlines to operate, so that Vietnamese have more options to choose, the quality will improve and more people can afford to fly around the country instead of using car, bus or train. It would be a further development for the better.
