CAAV will adjust the takeoff and landing frequency at the airport from 42 flights per hour to 44 flights per hour between 6 am to 11.55 pm and from 32 flights to 36 flights per hour between 0 am and 5.55 am.

With this increase, the country's largest airport will serve 60 more flights daily during those holidays.

The national flag carrier Vietnam Airlines will supply nearly 560,000 seats on over 2,800 flights on both domestic and international routes between April 26 and May 2.

Travel demand is forecast to rise by between 5-7 percent during the upcoming holiday and summer season.

The Ministry of Transport asked CAAV to prepare for peak season amid an aircraft shortage facing some major carriers.

National flag carrier Vietnam Airlines and low-cost carrier VietJet Air have reduced their flights using Airbus A321 aircraft since January, due to technical issues with Pratt & Whitney's PW1100 engines. Vietnam Airlines was forced to ground 12 of its planes, accounting for 20 percent of its narrow-body aircraft, for engine maintenance, which is set to last until 2025.

The country’s six airlines own about 170 planes, a drop of between 40 and 45 planes compared to the same period last year.

CAAV has so far granted operating rights to six domestic airlines with a total of 213 aircraft, meaning that local airlines can still rent aircraft for the coming peak season.

Many airlines are rushing to boost capacity and they may be able to add a number of aircraft to their fleets in early April.
