Before heading to Sea-Tac Airport currency exchange counters, compare current exchange rates online. Airport kiosks often charge high fees and offer lower rates. To save money, consider using a travel debit card or withdrawing cash from ATMs abroad. Some banks offer online currency orders with better rates—pick them up at the airport. Exchange only what’s needed at Sea-Tac and handle the rest at your destination. With simple planning, you can avoid extra fees and get the most value from your travel funds.
