Lufthansa has now broken the $1,300 roundtrip barrier for its premium economy, which offers 38 inches of legroom, footrests, upgraded meals and other nice perks. You must hurry: Tickets must be purchased by July 27 for departures between early August and November 30. A 14-day advance purchase and a Saturday stay are required. Cheapest prices are for midweek travel, of course, and weekend surcharges are about $100 each way.
