Upgrade with a Y-up economy-class fare
You’ll spend about the same as you would for a full-fare coach ticket but be automatically upgraded to first class upon check-in. Caveat: Y-up fares are not available on all flights (never for international travel) and can be highly restricted, making changes expensive or impossible. Book through a travel agent or use the Y-up tool on farecompare.com.
