My parents aged 79 and 74 were traveling with Lufthansa Booking Code# K2M9R3 from New Delhi, India to Seattle, WA. Departure date from Delhi 3 June 2019. They landed late into Frankfurt due to delay in departure from New Delhi. Their flight in FRA got rescheduled and Lufthansa changed their subsequent flights. They were put in a flight to Washington DC with a 1 hr 20 min layover to another connecting flight to Seattle. It is impossible for anyone to go through US Immigration, Customs, baggage and board the connecting flight with such a short layover. When we checked we were informed that the min time required for a connection was 1hr 15 mins. However please bear in mind that this is an international flight requiring lot more formalities and hence the time for changeover is impossible to achieve for anyone, let alone elderly passengers. They missed their connecting in Washington Dullas( IAD) and were rebooked in two separate connections: IAD-SFO and SFO-SEA. My parents who were to arrive at 11am on Jun 3 in Seattle reached 2am the next day - a delay of over 15 hours. Not to mention they now are in a domestic flight that had narrow seats. They were not provided any meals/refreshments/water post boarding at Washington. Their journey from DEL-SEA has become 36 hrs. It is extremely irresponsible of your agents to have re-booked senior citizens in a flight with ~1 hr connection. The customer care had been of no help when I requested to be connected to a ground agent. I have received no updates on what is going on. I am frustrated with such careless rebooking and need you to refund the full fare of the travel to my parents for the discomfort this has caused. --Deepa Krishnan Passenger#1: Vijayagopalan Subramaniam Passenger#2: Vijayagopalan Suganda Lufthasa booking code: K2M9R3
