Usually we issue the booking confirmation simultaneously with the E-ticket. It mostly takes up to few minutes to see the booking confirmation after payment has been made, with an option to send the Eticket to the preferred email address directly from the Confirmation Page.
If you did not get email automatically, double check you junk/spam folders and your email address provided.
In any case we will display the Order ID number with which to refer to us with the concrete problem, through Contact us.
