What is meant by OK to board ?
In short, OTB is a message entered in the airline's reservation system against your PNR number. It means that your paper-based visa (one that is not stamped in the passport) has been inspected and validated), and that airline check-in staff can issue you a boarding pass and allow you to board the flight.
How do I get OK to board ?
You have to submit all the required documents for applying for the visa. Once approved, your visa copy along with your return flight tickets will be sent directly to the respective airline to get OK to Board in your PNR. The airline will rectify your visa and flight tickets and issue OK to Board in your PNR.
