Keep spending your miles on Y tickets, and thank you for doing so. It means more award space for those of us who choose to redeem our miles for C/F tickets

BTW I'm a very proud redeemer of 120,000 UA miles for a Star Alliance First Class award ticket between SAN and HEL last summer. It was worth every single mile and since I value my miles at 1 cent per mile, it works out to 1200$ for a ticket that would probably have cost about 20,000$. Different strokes for different folks. ^
