Jet Airways and American Express are running a good promotion in case you are planning to make any flights in the coming days, a flat 20% off if you book with your Amex Card to fly on Jet Airways. The promotion is valid for domestic as well as international flights of the airline.
The promotion is valid on the India country site of the airline, which you can access here. The 20% discount is applicable on base fare on flights within the country as well as abroad, but originating from India. Tickets purchased until February 7, 2017 are going to get this discount. For international flights, travel can start anytime, but for domestic flights, travel would have to commence at least 15 days after booking the tickets. Discount is valid only on American Express cards issued in India. Promotion code JETDAX20 needs to be applied for domestic tickets and JETIAX20 for international tickets. You could use any American Express card, not just the co-branded one.
For international flights, you would actually be saving substantial money. Take a look for instance on a random flight pricing from Mumbai to Hong Kong in February 2017.
I’d recommend if you have any flights to book for this year, maybe now is a good time to plan it out and lock it in. 20% off is a very liberal deal! The last such promotion had a restriction to travel in March 2017, but this one has no time limits.
