Sanaʽa International Airport is Yemen's main domestic and international airport, handling 80% of all air passengers in the country in 2007. The airport sustained has heavy damage during the ongoing conflict in Yemen, and has been closed for commercial flights since August 2016. This has prevented many Yemenis from being able to travel abroad to receive medical treatment. In addition, at the start of the Saudi blockade, the Sanaa airport was completely shut down for 16 days until being reopened to humanitarian flights on the 22nd of November.
