I am traveling from Pakistan to Bangkok on Etihad Airways. I have a transit at Abu Dhabi of 12 hours. Can I go out of the airport to spend the time in Abu Dhabi? I am holding a Pakistani passport. It will be my first trip so, I am not sure what are the rules and regulation.
You can leave the airport only with a Transit Visa. Refer to these links
Also, Etihad airways is also providing for transit visa. Refer to this website for more details. I think its best to consult the airline website in these cases.
