So, you both are saying that even though I have a spelling error AND a name transposition, I should be OK?
YES.
I have read that the airport procedures (admittance to terminal, check-in, security) can be very strict in India. I am willing to push back with the tour operator and insist they reissue the ticket, unless I can be absolutely certain that I won't have any trouble.
Usually, the pax name cannot be modified, unless, its a transferable fare / booking. Simply, call and confirm with the airline and you should be fine.
As a thumb-rule, always sit down with a copy of the passenger' travelling documents while making a booking. If you use a TA to book it, send them an email with the correct spellings and cross-check before making the payment.
You should be thankful, you weren't flying RyanAir..!!
