OTB means OK To Board and is a part of the process for acquiring a Dubai visa. Upon approval of the visa by immigration, a copy is sent to the airline the traveler has booked their UAE flight tickets with. After evaluation, the airline marks the flight PNR as OK to Board, without which the traveler shall not be allowed to board the flight for the Dubai tour.
