Millions of people are expected to flock to Hanoi to watch the military parade and troop review on Sept. 2 to mark the 80th National Day.
Flights from HCMC to the capital at convenient hours between Aug. 30 and Sept. 3 cost VND5.6-6.5 million two-way as against the regular fare of less around VND2 million.
Hotels in downtown Hanoi are never full during holidays, but now there is a shortage of rooms, particularly in prime locations.
Hotels in central areas like the Old Quarter and near Ba Dinh Square have reached 85-90% occupancy rates in the four- and five-star segments and 80% in the three-star segment.
Flights to Da Nang now cost VND3.8-4 million from Hanoi and VND3.4 million from HCMC, equivalent to the fares during the peak summer holidays in June.
Airfares to Phu Quoc Island have also shot up, costing VND5.4-8 million, or higher than fares to China and Thailand.
But hotels on Phu Quoc are experiencing occupancy rates of just 30-40% across all segments.
