I l a p flight Kochi to indore for 13th of june 2017. It is two different flights one Kochi to mumbai and other mumbai to indore. Due to sinecreasons I won't be able to travel Kochi to mumbai. But I want to take the mumbai to indore flight. Which they say is against their policy. I don't understand what stops me from taking the mumbai to indore flight if I have paid for it. I have attached the screen shot of tickets here. It clearly shows two different flight numbers.
