The demonetization in India in November 2017 also allowed the airlines to offer a promo to increase their ticket sales, as they were allowed to accept the demonetized Rs 500 and Rs 1000 notes.
Due to identity theft and impersonation frauds of the all powerful, extremely corrupt CBI, NTRO, indian intelligence and security agencies, harmless vulnerable indian citizens were losing their faith in the banking and financial system controlled by brahmins and banias, preferring to keep their money in cash.
After demonetization many had a lot of cash at home, and instead of depositing in the bank to be harassed by the corrupt greedy intelligence and security agency officials, they decided to purchase air tickets.
Some airlines like Spicejet were advertising their promotion for airline tickets extensively on newspapers and television channels, openly stating that they were accepting the demonetized Rs 500 and Rs 1000 notes in their advertisement.
