Given the goal of Europe this summer, if there are saver level seats available one way on AA and partners (most except IB in this case can be searched at AA.com - be aware that BA flights will incur high surcharges) and the other on UA and partners (searchable at united.com), you could transfer 60K Chase UR to UA and 8K SPG to AA and book.

+1 to all the other advise. You have done the easy part and now it's time to learn how to use those miles, or decide that's too much work and pay an award booking service ~$100 per person to figure it out. We will gladly help you learn to fish if you are willing to read and research. Welcome to flyertalk!
