Translation of mud in Spanish

The airport was huge, compared to Siem Reap's one, of course. We expected something similar to Bangkok's airfield but it was completely different. We stood in line for the passport control.
how are you? Where do you live in Austria? I hope your Spanish is good enough that you understand my sentences! If you can't understand it i will write this in English. I live in Munich, btw.
The bus left on time to the border town Tacna. Crossing the border was also an experience. We needed to show our passports about seven or eight times and were checked for goods three times.
