Lufthansa will introduce a three-tier fare structure for European international routes and domestic Germany routes, the carrier announced this week.

The structure, available for sale this summer for service beginning in the fall, will include the Light fare, which has no checked baggage allowance and no rebooking and does not let travelers select seats until 23 hours before departure; the Classic fare, which allows one free checked bag, rebooking for a fee and seat selection upon booking; and the Flex fare, which allows rebooking and is refundable for a fee. By the third quarter of this year, Lufthansa also plans to complete a €1.5 billion retrofit of its long-haul aircraft fleet, and its Premium Economy class by year-end will be available on all intercontinental flights, according to the carrier.
