I received a bonus travel certificate in exchange for willingly (volunteering) to take a later flight. I would like to use the value of that certificate towards a summer trip to Europe (somewhat open to arrival city). I would ideally originate from a Bay Area airport like SFO or SJC. Since Alaska doesn't fly to Europe it seems I would need to find a routing that has Alaska for at least one flight segment so I can buy the tickets through Alaska Airlines and use my travel certificate funds. The challenge is in finding these routings. I haven't had any luck using Google Flights even though that was how I got the original Alaska itinerary (which was just one leg on Alaska and the rest on Copa). Any guidance would be appreciated. Thanks in advance
