I had booked about 5 months before my trip to India which ended a few days ago.. I bought a return ticket from Amsterdam to Lucknow via London and Delhi.. Onward journey went good.. My return journey was after a month.. At the last moment when I was checking in in Lucknow for Delhi, I was informed by Vistara Airlines if I knew about my flight from Delhi to London at 03000hours was cancelled and rebooked to leave Delhi at 1055 instead of 0300 as was originally booked by me. I was not informed.. British Airways had my email address and my mobile number.. They never called me and I never received any email about the change.. I am 81 years old person... British Airways expected me hang around for about 18 hours to board BA flight to London!!!. When I talked to their customer service and requested to provide me hotel accommodation or entry to lounge at the airport they refused.. My son who lives in Mumbai also requested Customer service of British Airways to help his 81 years old father with night accommodation so he could rest, they refused... I was so distressed and my BP shot up..I could have died.. They didn't care for my life at all...
