Travelers are stranded as far away as Australia, Brazil and the Maldives after the U.S. and Israel launched strikes on Iran this weekend. With airspace in the region still closed, getting home could be a challenge at least several days.

Here’s what to know:

Around 3,000 flights have been cancelled since the conflict in Iran began Saturday and subsequent attacks by Iran continue to impact other parts of the region, according to aviation-data firm Cirium.

Airspace was closed over a large swath of the Middle East, suspending flights to and from Dubai International Airport, one of the busiest hubs in the world, Tel Aviv, and Doha, Qatar. More than 40 flights were forced to divert early Saturday morning after the attack prompted airspace closures in the region.
