The best transport for traveling between cities in Vietnam

I think that the best transport for traveling from one city to another city in Vietnam is the airplane. People can save a lot of time when they travel by air. For example, it takes them about 37 hours by train but only 2 hours by airplane to travel from Ho Chi Minh City to Hanoi. Moreover, it is much safer to travel by airplane than any other type of transport. At customs, people scan all passengers’ luggage through an X-ray machine before they get on the plane. Also, passengers can’t bring any sharp objects, such as knives, scissors, and many other dangerous items on the plane to ensure security. To many people, flying is relaxing. They can enjoy their flight with food and drink served. They can even entertain themselves by watching movies available on the plane. To conclude, no other type of transport is better than airplanes to travel between cities in Vietnam.
