A U.S.-Israel military campaign against Iran escalated Saturday, triggering retaliatory strikes across the region and prompting new airspace restrictions that are disrupting civilian travel.
As governments move into emergency posture and commercial routes narrow, Tampa-based Greybull Rescue says it has positioned operators in multiple Middle Eastern countries to prepare for possible evacuations of Americans.
In a Feb. 28 statement distributed by email, the veteran-led nonprofit said its teams are “boots-on-ground” and “setting conditions for mass evacuations of Americans” as flight options contract.
Regional travel disruptions can escalate quickly when airspace closes or airlines suspend service, as airports halt departures, borders tighten and overflight corridors shift with little notice, leaving travelers who planned routine departures facing delays or cancellations.
Greybull said exit routes are narrowing.
“Safe exit routes are disappearing fast,” the organization wrote. “Airspace is closing all over the region.”

The group said it has operators and assets positioned in Israel, Jordan, the United Arab Emirates, Lebanon and Saudi Arabia and is “surging additional resources, manpower, ground assets and aircraft” into the region.
Greybull did not disclose how many Americans have requested assistance, whether evacuations are underway or what coordination, if any, is occurring with U.S. officials.
As of Saturday evening, the State Department had not issued a mandatory evacuation order for all U.S. citizens in the region, though it did direct the departure of non-essential personnel from the U.S. Embassy in Beirut and issued security alerts for Americans abroad.
The nonprofit said donations fund aircraft costs and fuel, ground logistics and security, intelligence support, secure communications and medical evacuation planning.

A Tampa-based operation in a fluid region
Saturday’s escalation represents one of the most direct confrontations among Iran, Israel and the United States in decades. Military exchanges and retaliatory threats have raised concerns about broader regional instability.
For civilians and expatriates, the immediate issue is access, since commercial aviation remains the primary evacuation pathway in most crises.
Commercial aviation remains the primary evacuation pathway in most crises. When that pathway constricts, governments may issue advisories, charter aircraft or coordinate military-assisted departures.
Private operators sometimes move in parallel, particularly for individuals who do not qualify for government extraction or who seek independent arrangements.
Greybull’s announcement places the Tampa-based nonprofit within that space.
Whether broader evacuations become necessary will depend on how the conflict evolves in the coming days. For now, Greybull says it is positioned in-country should conditions deteriorate further.
