Traveling through Mehrabad with children is manageable, but it requires more planning than most airports simply because of how things work in Iran.
The airport itself
Mehrabad is compact compared to international mega-airports. The walk from the gate to baggage claim is short, which helps when you are carrying a sleeping child. Trolleys are available at the carousel area. There are basic facilities like restrooms and a small shop, but do not expect family lounges or extensive dining options. Get through the terminal and into your vehicle as quickly as possible.
The car seat situation
This is the biggest concern for families. Child car seats are essentially nonexistent in Iranian taxis. Regular airport taxis, Snapp, Tapsi, none of them provide car seats as standard. Iran does not have the same child restraint laws as European countries.
If a car seat is important to you (and it should be for young children), your only reliable option is to book a private transfer and specifically request a child seat at the time of booking. Even then, confirm the request a day before your flight. Alternatively, bring your own travel car seat. Compact, portable models like the BubbleBum or mifold work well for this.
Vehicle and luggage considerations
Standard Tehran taxis are sedans with limited trunk space. If you are traveling with a stroller, two suitcases, and carry-on bags, it will be a tight fit. A family of four with typical vacation luggage really needs a larger vehicle. When booking a private transfer, request a van or SUV if your group has more than two large bags.
The language factor
Children make the language barrier both easier and harder. Drivers tend to be friendly and accommodating when they see families, but communicating specific needs (temperature, stops, route preferences) remains challenging without Farsi. Having your hotel address written in Farsi on your phone is essential. A private transfer driver will typically have received all this information in advance.
Practical recommendations
For families with children under 5, book a private transfer with a car seat request. For families with older kids, any option works, but a private vehicle avoids the squeeze of a standard taxi. Pack snacks and water for the car ride, as Tehran traffic can turn a 20-minute drive into an hour during rush hours. If you have a connecting domestic flight from Mehrabad, note that the terminals are separate buildings, so allow extra time to move between them with children and luggage.
One more thing
Iranian people are genuinely warm toward children. Do not be surprised if your taxi driver offers your kids candy or tries to entertain them despite the language gap. The cultural hospitality is real, and it makes the journey more pleasant for everyone.
