Memmingen, Weeze, Hahn: when Germany's secondary airports are worth it

Search flights from "Munich" and you will never see the fares leaving 110 kilometers away in Memmingen, where Ryanair and Wizz Air run some of southern Germany's cheapest departures. Low-cost carriers love secondary airports because the fees are lower, and they pass enough of that on to make the detour worth checking. The trick is knowing when the detour actually pays.

The airports worth knowing

• Memmingen (FMM): the de-facto low-cost airport for Munich and Stuttgart's south. Strong Ryanair and Wizz network to Spain, Italy, the Balkans and Eastern Europe.
• Weeze (NRN): Ryanair's base near the Dutch border, an alternative for the Ruhr and Cologne region, often dramatically cheaper than Düsseldorf on the same routes.
• Frankfurt-Hahn (HHN): despite the name, 120 km from Frankfurt. Worth it mainly with your own car or when the fare gap is large.
• Dortmund (DTM) and Karlsruhe/Baden-Baden (FKB): smaller Wizz and Ryanair bases with standout fares to Southeast Europe, especially the diaspora routes.

The door-to-door math

A cheaper fare only wins if it survives the transfer. Add the bus or train to the airport for every traveler, both directions, plus the extra time. A €40 saving per person on a family of four is €160 and clearly worth a one-hour bus; a €15 saving for a solo traveler with a €20 transfer is a loss.

Two habits keep the math honest: always compare the same dates on the nearby major airport, and check the return leg's arrival time, because a 23:30 landing at a secondary airport can mean no public transport home.

Search them without the spreadsheet

A Plavion search checks carriers that fly from the secondary airports alongside the majors and returns everything as one cheapest-first list with direct booking links, so the Memmingen fare and the Munich fare sit next to each other with real numbers. The route price pages show what each route typically costs by month, which makes a genuinely cheap secondary-airport fare easy to recognize.
