The airline is the world's fifth-largest airline in terms of overall passengers carried, operating services to 18 domestic destinations and 183 international destinations in 78 countries across Africa, Americas, Asia and Europe. Together with its partners Lufthansa services around 410 destinations. With over 722 aircraft it has the third-largest passenger airline fleet in the world when combined with its subsidiaries.

Lufthansa's frequent-flyer program is called Miles & More, and is shared among several European airlines, including Austrian Airlines, Adria Airways, Croatia Airlines, LOT Polish Airlines, Luxair, Swiss International Air Lines and Brussels Airlines. Miles & More members may earn miles on Lufthansa flights and Star Alliance partner flights, as well as through Lufthansa credit cards, and purchases made through the Lufthansa shops. Status within Miles & More is determined by miles flown during one calendar year with specific partners. Membership levels include: Basic (no minimal threshold), Frequent Traveller (Silver, 35,000 mile threshold), Senator (Gold, 100,000 mile threshold, 130,000 for German residents), and HON Circle (Black, 600,000 mile threshold over two calendar years). All non-basic Miles & More status levels offer lounge access and executive bonus miles, with the higher levels offering more exclusive benefits.
