Pair programming is fantastic. There is no better way to educate a newer team member to code standards and procedures as well as business domain. It also helps to reign in over-engineering and bad approaches. For more senior developers, it can expose them to newer approaches and technologies that they might not be aware of. I had a great experience pairing on a complex feature request (convert desktop version of an app to a mobile version) that was planned for 3 months. We finished it in a month with full test coverage and every little change to PM, PO, and UX designer could throw at us. Because we both had knowledge of the systems, we could later work independently on simpler tasks and regroup later to combine our efforts.
