Air India Alters Elderly Couple’s US Flights Without Notice

Air India Alters Elderly Couple's US Flights Without Notice

An elderly couple’s travel plans were unexpectedly disrupted when Air India allegedly changed their tickets and destinations without prior notification, as reported by a user recounting the ordeal.

According to Dushyant Arora, the couple discovered the changes only when they attempted to check in for their flight to Newark, New Jersey, scheduled for June 19.

They were shocked to find that Air India had booked them on separate flights. The husband was re-routed to New York instead of Newark, departing on a different day than originally planned, while the wife’s itinerary remained unchanged.

The couple, unfamiliar with the changes and concerned about flying separately, decided to cancel their tickets. This decision was particularly difficult for the mother, as it would have been her first time flying abroad, and she expressed reluctance to travel alone.

The couple was not contacted by anyone from the airline to inform them of the changes. The tickets had to be cancelled by the couple. In response to the X user, Air India stated that the customer’s request for a complete refund has been fulfilled.

“Dear Sir, we apologise that this happened and assure you that we never plan to interfere with our clients’ travel arrangements. “We have conducted a complete refund in accordance with the primary customer’s request, who was booked in the PNR,” stated Air India.
