Got it.
I went to ITH Delhi office with my vouchers but they did not agree to deposit them. So I'll probably have to visit again when I actually have to book the tickets.
I came to know that United very rarely show AirIndia flights.
And I read that there's a phantom availability issue with Vistara in UA, where it will show the seats available but the booking doesn't go through.
Is anyone having a better insight on UA?
My script is only for Magnus... it's actually not much different that Sidd's original script. I have just added the ability to capture the currency from the email to excel sheet ( Which, as per the last comment, Sidd has done in his script as well).
I am still using your original code as of now, maybe you added this currency conversion in your more recent revision? Because in the older version of your code the currency was not being captured in excel so I had to made some changes to your script.
