Seems like you guys haven't tried Fold Money yet. It's quite amazing. It has the option of automatically tagging all your expenses via the transaction emails you get without giving full access to your email account. Try it out.

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?
