Yes, Alaska Airlines does fly internationally, but its routes are mostly limited to nearby regions. They offer service to places like Canada, Mexico, Costa Rica, and Belize, with most flights departing from West Coast cities. Their international network isn’t as large as the big global carriers, but it covers popular vacation spots and practical cross-border routes. Many travelers use Alaska’s partner airlines for longer international trips, since those partnerships allow booking to Europe or Asia through Alaska’s website while still earning miles. Overall, Alaska’s own international flights are regional but useful if you’re traveling within North America and Central America.
