Yes, you can put a travel iron in your suitcase, and they are permitted in both checked and carry-on luggage according to 2026 TSA and international security guidelines. Unlike items with internal combustion or certain lithium batteries, electric irons do not pose a significant safety risk during flight as long as they are turned off and unplugged. However, many modern travelers find that travel irons are becoming less necessary due to the prevalence of handheld garment steamers, which are gentler on delicate fabrics and often more compact. If you do bring an iron, ensure it is a "dual-voltage" model if you are traveling internationally, as a standard 110V American iron will likely blow a fuse or melt when plugged into a 220V European outlet without a heavy-duty transformer. Additionally, you should allow the iron to cool completely before packing it next to synthetic fabrics in your suitcase. As an alternative, almost all mid-range and luxury hotels provide a full-sized iron and ironing board in the room or upon request, so you might save valuable luggage weight and space by checking your hotel's amenities list before you pack.
