Any recent experiences trying to book award tickets out of JFK to HND/NRT in F or J? Seemingly impossible to find ANA saver availability on UA, even as far out as possible. Any tips or suggestions? I'm aware of T-330 and booking a round trip to return the next day, just to secure the outbound and eat the $50 change fee. Am I better off looking for availability out of IAH or ORD? Any advice is appreciated - thanks.
