In June 2023, the US FAA cancelled a four-year long ban on overflights of Venezuela below FL260. The applicable KICZ Notam expired in June, and hasn't been renewed. This essentially ends all restrictions on the enroute use of Venezuelan airspace - no other states have active airspace warnings in place for the SVZM/Maiquetia FIR. Any aircraft planning on using it though still need to consider the possibility of diversions - crew and passenger safety would be a major issue on the ground. The US Department of State maintains its highest level of travel warning for Venezuela due to a risk of crime and kidnapping.
