Yes. International flights to Shanghai depart from Imam Khomeini International Airport (IKA), not Mehrabad. Be at the correct terminal about three hours early and allow extra road time from central Tehran.
A nonstop Tehran–Shanghai flight is usually scheduled for roughly eight hours, although wind and routing can change the actual time. Connecting options take considerably longer, so compare the complete journey and layover rather than only the fare.
Tehran services normally use Shanghai Pudong International Airport (PVG). Shanghai Hongqiao (SHA) is a different airport used mainly for domestic and regional flights, so always check the airport code—especially when arranging a connection or pickup.
Pudong is about 30 kilometres from downtown. Metro Line 2 is economical and takes about an hour to People's Square; taxis are often around 50 minutes in normal traffic, while the Maglev reaches Longyang Road quickly but still requires an onward transfer.
Carry a passport valid for the trip, the appropriate Chinese visa or entry permission, and any supporting documents required for your travel purpose. Verify the latest official rules for your nationality before booking because transit and entry conditions can change.
Shanghai is 4 hours 30 minutes ahead of Tehran. Check the local arrival date carefully when reserving accommodation, transport or a trade meeting, particularly if the flight leaves Tehran in the evening.
Treat a PVG-to-SHA transfer as a change of airport, not a normal airside connection. The airports are about 40 kilometres apart; allow several hours for immigration, baggage, transport, check-in and disruption, and avoid separate tickets with a tight same-day gap.
Only if the itinerary and airline agreement permit it. Ask at check-in and read the bag tag; you may still need to collect baggage for customs and recheck it. Separate tickets usually carry more risk because the next airline may not protect you after a delay.
Before departure, save the hotel name and address in Chinese, arrange a payment method that is likely to work locally, and keep essential confirmations offline. Check roaming, local connectivity and access to the apps you depend on rather than waiting until arrival.
