The CEO of Vietnam Airlines (VN, Hanoi Noi Bai International) says he will have to ground twelve of its twenty A321-200Ns because of Pratt & Whitney engine issues, according to a VnExpress report. Le Hong Ha told the outlet he expects the aircraft, which make up 20% of the carrier's fleet, to be out-of-service for up to 300 days because supply chain disruptions have doubled the maintenance time.

According to the VietnamNet.vn outlet, the Civil Aviation Authority of Viet Nam (CAAV) has told its carriers to have backup plans to cover the number of out-of-service aircraft. In addition to its A321N fleet, VietJet has twenty-two A320-200s (one inactive), including four wet-leased A320-200s; thirty six A321-200s (one inactive); and seven A330-300s.

Competitors Bamboo Airways (QH, Hanoi Noi Bai International) and Vietravel Airlines (VU, Hue Phu Bai International) do not operate any A321neo. However, ch-aviation data shows four of Bamboo's 11 aircraft are out-of-service, including two A320-200s, one A320-200N, and one A321-200. Bamboo has wet-leased two A320-200s to help cover the capacity shortfall. Vietravel Airlines has just three A321-200s, and all are active.

The Vietnamese-language outlet says CAAV is "requiring domestic airlines to proactively plan their operations and have backup plans to supplement the shortage of aircraft."
