I was booking a train ticket from delhi to trivandrum on 19th may and it cancelled because of the lack of available seat. But that booking was under trip guarantee and i got a voucher code. And i tried to apply it on flight ticket on 26th may 2023 but it shows an error this promocode is not applied the moment. I lock a price and it ends today 3pm. Flight price go high. So do the need ful.
