Translation of bunker in German

We decided according to whom we liked most and booked a trip for the next day. We looked for a place for lunch and found a restuarant called Pho 24, where they would serve soups for 24 hours.
A flew hours later we landed in Siem Reap. The land around us was amazingly green and the weather was very humid. We were still in shock while driving into the city center with our driver.
We arrived at the airport two hours prior to our flight with no seat guaranteed. As these are local flights, the counters open just 1 hour before take-off. The alternative root would be by bus.
