I was on a flight last month from BKK - Ubon with Viet Jet, around 5 min prior to landing the engines went to full power and could hear the landing gear being retracted, 10 min later was informed plane was returning to BKK due to rain storm at Ubon.
Heading back to Chaing Rai on the 9th with Viet Jet, so will need to wait and check what happens.
