So I got my visa 15 days after submitting the documents. My flight itinerary was legit but it expired 3 days after I booked (before submitting the documents to the embassy).
Embassy issued the visa so if your all the documents are original but flight itinerary is expired, you can get the visa as the embassy also knows that no one is going to buy a full ticket before their visa.
Hope this will help others.
