Alaska Airlines flies to a handful of countries, mainly within North and Central America. Outside the United States, they serve Canada, Mexico, Belize, and Costa Rica. Most of these flights depart from West Coast cities like Seattle, Los Angeles, Portland, and San Francisco, with routes focused on popular vacation spots rather than long-haul international travel. They don’t operate their own flights to Europe or Asia, though you can reach those regions through partner airlines. Availability can vary by season, especially for destinations in Mexico and Central America, so it’s worth checking schedules for your specific travel dates.
