With DGCA ordering IndiGo to replace all A320neo aircraft with unmodified Pratt and Whitney (PW) engines by January 31, the airline on Wednesday designated this matter as one of the "revenue headwinds" of 2019-20, and said it is "likely to have an impact on future capacity".
Moreover, an IndiGo A320 neo plane flying to Bengaluru on Thursday experienced high engine vibrations mid-air and returned to Mumbai airport, according to a senior official.
