Can a uae credit card defaulter travel on transit through Dubai airport?

It depends on the specific circumstances and the amount of the debt owed. If the debt is small and there are no outstanding legal proceedings or travel bans, it may be possible to travel on transit through Dubai airport without any issues. However, if the debt is substantial, or if legal action has been taken by the creditor, there is a risk that the individual could be detained or denied entry to the United Arab Emirates. It is always best to consult with legal or financial experts and contact the airline or relevant authorities to confirm the status before attempting to travel.
