Several Vietnamese airlines have wet-leased aircraft to prepare for soaring travel demands during the upcoming Lunar New Year holiday, or Tet, in February. Low-cost air carrier Vietjet received its fourth wet-leased aircraft on Monday evening, bringing its fleet of airplanes to 107 ahead of Tet. The same day, Bamboo Airways received a wet-leased aircraft at Tan Son Nhat International Airport in Ho Chi Minh City, which it will use to help appease travel demands during the holiday. In addition to leasing additional aircraft, many local airlines are increasing their nighttime flights in order to serve more local and international travelers. Conversely, a 'dry lease' involves only the leasing of the aircraft itself, with no additional crew or services.
