Iran Air cannot legally fly to or from the United States. Comprehensive US sanctions on Iran cover the aviation sector. No US airport ever sees an Iran Air aircraft.
No US travel agent can issue an Iran Air ticket that starts or ends on US soil. This page on Iran Air baggage allowance exists mainly to explain that limit. The airline publishes no allowance a US traveler can rely on for a US departure.
Why Iran Air does not serve the United States
The US Treasury maintains a broad sanctions program against Iran. It names the aviation sector specifically. Iran Air has been a repeated target of that program for over a decade.
A traveler who wants the current legal position can read the Treasury’s own summary of the Iran sanctions program. That is a better source than any airline’s own claims. Iran Air does not sell tickets that touch a US airport, and no code share changes that.
What this means for the Iran Air baggage allowance question
A US citizen can still fly Iran Air, just never on a route that begins or ends in the United States. The typical pattern is a flight from a third country. Istanbul, Dubai and European hubs are common gateways onward to Tehran.
US sanctions law generally restricts US persons from most transactions with Iran. Anyone weighing this trip should treat the Treasury guidance above as the source of truth. A forum post or a travel blog is not a substitute.
Connecting itineraries and whose bag rules apply
A US traveler sometimes books a through ticket. One segment runs on a US or European carrier, and a later segment runs on Iran Air abroad. Under standard IATA interline practice, the marketing carrier that issued the ticket usually sets the checked bag rule for the whole trip.
The strictest single leg often governs the final weight and piece limit. A traveler on this kind of itinerary should confirm the rule with the ticketing airline before departure. It also helps to understand how checked baggage allowances interact across partner carriers on one ticket.
The cabin bag question is simpler. Most travelers on a mixed itinerary size their carry on to the strictest single leg. That choice keeps them clear of a gate check on any segment.
What independent reports actually show
Iran Air carries no US origin traffic. The pool of American forum reports this site normally checks for enforcement patterns is thin as a result. What does surface in traveler discussion of Iran and its neighboring carriers points to a familiar regional habit.
Gate agents on older, smaller aircraft weigh cabin bags more often than the written policy implies. An oversized roller bag tends to get tagged at the jet bridge rather than the counter. That pattern shows up across several Middle Eastern carriers, not just this one.
Sizing a bag before any trip involving Iran Air
Iran Air’s own website could not be read when this page was checked. No carry on dimension or weight limit here comes from the carrier directly. The safest approach is to pack toward a tight common standard rather than guess at a number.
Running a bag through a general size checker before departure catches most surprises. Reviewing general carry on rules for the connecting carrier is the more reliable move for the US leg of the trip.
A traveler flying onward from a European gateway should also check that hub’s own carry on size standards. EU based connecting carriers sometimes enforce a stricter cabin limit than US carriers do.
What is not confirmed on this page
This Iran Air baggage allowance page does not carry a single figure taken from it. No guessed carry on size, checked weight or bag fee is published here.
That follows this site’s editorial policy on unverified figures. Anyone with an active Iran Air booking should confirm a firm number with the airline or a travel agent at booking time. This page is not the source for a specific dimension.
The bottom line
The real Iran Air baggage allowance question for most American readers is not what the airline allows. It is that the airline cannot be part of a US itinerary at all under current sanctions. Anyone flying Iran Air does so entirely outside the United States, on a route that starts and ends elsewhere.
For the US portion of any connecting trip, the ticketing carrier’s own baggage fee schedule is what actually governs the bag in hand.
