Tour companies are having a bumper holiday season, with most out-bound and in-bound tours sold out for Reunification Day on April 30 and the May Day holiday on May 1, with few slots left for remaining travel.
Many tourism firms report the demand for this year's long six-day holiday is up sharply on previous years, and popular tours sold out two months ago.
Travellers have been attracted by the long holiday break, attractive promotional campaigns and discounted tickets. The recent spate of hot weather has made sea and mountain resorts extremely popular.
Unlike Tet, when family commitments occupy much of the holiday break, Reunification Day and May Day allow people to simply enjoy themselves, tour companies say.
Vietravel Company said it had taken bookings from 20,000 customers, up 50 percent on last year. CP Hanoi Redtour reported 6,000 customer, an increase by 30 percent.
Many firms are seeing an average 50 percent jump in business.
Representative from Vietnam Airlines said 545 flights have been added during the April 25 to May 4 period, an increase of 17.8 percent on normal schedules and 82.9 percent more than last year.
"The most sought-after flights are from Hanoi and HCM City to Danang, Phu Quoc and Nha Trang," he said.
Vietnam Airlines has added 106 flights to Phu Quoc Island, but with the boost in ticket sales the airline is worried about airport congestion and the increased likelihood of delays.
Jetstar Pacific has increased flight numbers, but has been unable to meet demand.
There has also been a surge in demand for rail and bus tickets, with more staff being added for the holiday period to handle increased frequency of services.
