  • Further smoke-alert diversions or technical incidents involving Air India Express aircraft in the coming weeks.
  • Complete engineering inspection of the cargo-hold smoke detection system and release or ground the aircraft based on findings.
  • Deploy the alternate aircraft, rebook disrupted passengers, and manage accommodation, meal, and compensation obligations where applicable.
  • Review maintenance logs and recent fault history for the aircraft and any common components across the relevant fleet subset.
  • Communicate that the diversion was precautionary and that no smoke or fire was found, while providing passengers with revised departure information.
