Germany's flag carrier accepts non-electric Bromptons as checked sports equipment on all routes. With a generous 280cm linear size limit and 32kg maximum, a Brompton in a proper travel case sits comfortably within their limits. The catch that trips riders up: you must pre-register with Lufthansa's Service Center at least 72 hours before departure — show up without it and you risk being turned away at check-in. A sports equipment fee applies unless your fare already includes a checked bag. For non-electric Bromptons, Lufthansa is one of the most consistent and predictable European carriers to fly with.
