PORT-AU-PRINCE, Haiti (AP) — Haiti’s main international airport reopened Monday for the first time in nearly three months after relentless gang violence forced authorities to close it.

The reopening of the Toussaint-Louverture airport in the capital of Port-au-Prince is expected to help ease a critical shortage of medications and other basic supplies. The country’s main seaport remains paralyzed. Gangs control 80% of the capital.

U.S.-based airlines are not expected to start using the airport until late May or early June.

The first commercial passenger flight since March left for Miami nearly two hours behind schedule, with sweating passengers complaining about the lack of air conditioning until takeoff. Although the flight was organized by local carrier Sunrise Airways, it contracted Florida-based charter airline World Atlantic, which distributed paper towels to drenched passengers.
