I meant that whether the Air bubble agreement would allow going via Dubai or Qatar for going to Serbia, I booked a ticket via Dubai to Serbia but the Air Bubble agreement with UAE and Qatar states that passengers can only transit if their destination is in Africa or South America. So, now I don't know what to do.
Please call your airlines.
I called Emirates yesterday and they confirmed that Dubai is open for transit to Europe.
The agent categorically said that the transit should be less than 10 hours.
Please do call your airlines; and enquire if you can transit Dubai.
My answer is "Yes, you can."
But do call your airline and be sure that you can transit with the specific booking.
If your transit in Dubai is less than 10 hours, you do not need to worry at all.
