Flight connection at Abu Dhabi Airport (AUH)

I am holder of passport of Uzbekistan. I plan to fly via Abu Dhabi airport (AUH). Two flights are served by the same airline - Wizz Air Abu Dhabi. I am flying without checked baggage, so I do not need to recheck it at AUH. The first flight arrives to Abu Dhabi at 01:10 AM, the second flight departs from Abu Dhabi at 22:10 PM (the same day). Time between flights is 21 hours. I have these questions:

Is it possible to transfer without crossing border (passport check) from the first gate to another gate? If yes, do I need to get transit visa in this case?
Can I get free 48h transit visa to visit Abu Dhabi or Dubai? I found that passengers of UAE flag carrier airlines (e.g. Emirates) can get free 48h transit visa, but I could not find information for Wizz Air Abu Dhabi.

Can I transit through AUH?

Re: 10 layover at AUH airport need transit visa?? You do not need a visa to stay at the airport. A transit visa is only required if you clear immigration and plan on leaving the airport, in which case it will depend on your nationality if a Transit visa will be given to you. Indian Nationals do not get visa on arrival.

Re: 2 hour 30 minute transit in Abu Dhabi for USA, is it enough? You should be fine... Just take into account the extra time that US Customs and Border Pre Clearance will take... Essentially, you will take care of all immigration and customs formalities at the Abu Dhabi Airport before you board the plane.
