SLG

What SLG does

SLG is a Luxembourg-based private mobility group, founded in 1948 through its subsidiary Sales-Lentz, that operates a multi-brand portfolio of passenger transport, airport shuttle, travel agency, and tourism services. The group is controlled by the Sales family, with Jos Sales and Marc Sales serving as managing partners, and is headquartered in Bascharage, Luxembourg. SLG operates through 10 wholly-owned subsidiaries across Luxembourg, Belgium, Italy, and the United Kingdom, including Sales-Lentz (bus transport with 1,200+ drivers), Flibco (airport shuttles, majority stake divested to Flix in January 2026), TravelPro, Léonard Travel International, Keywi, and tourism brands such as Sightseeing.lu, Nightrider, LetzRide, Coolbus, and Dinnerhopping. The group employs more than 2,000 people and serves over 1,700 colleagues in Luxembourg and over 300 internationally.

The underlying technology is a mobility management platform combining passenger transport operations, digital booking systems (including flibco.com, sales-lentz.lu, travel-pro.lu), and fleet management across multiple brand sites. Infrastructure assets include 120+ electric buses, 240 charging points, and a 354 kWp photovoltaic installation at Bascharage headquarters (2,215 modules, 190 MWh annual output), positioning the group as a regional leader in sustainable mobility. SLG also operates Keywi as an in-house digital booking platform and has implemented the SQUARE internal communications platform based on Microsoft 365. Flibco introduced a four-day workweek with full salary in 2023 as an HR innovation.

Revenue is generated through three primary streams: transactional passenger transport fees (bus transport, airport shuttles, school transport, services for people with reduced mobility, regular shuttles), recurring public transport contracts with government authorities, and travel/tourism transaction fees through travel agency brands. The group pursues a hybrid go-to-market combining direct-to-consumer digital booking platforms, enterprise field sales for corporate and government clients, and travel agency retail locations. SLG does not publicly disclose revenue, and no external institutional investment or private equity backing is evidenced in available materials.

Direct peers

• Flix (FlixBus / FlixTrain): Munich-based long-distance coach and train operator that in January 2026 acquired a majority stake in SLG's Flibco airport-shuttle subsidiary. Flix is the most direct competitor and now-partner in the European airport-coach segment, operating overlapping routes across Belgium, Italy, and the UK.
• BlaBlaBus (BlaBlaCar): Long-distance bus service operated by BlaBlaCar that competes directly with FlixBus and Flibco on intercity and airport routes across France, Belgium, Germany, and wider Western Europe—comparable digital-led coach model targeting price-sensitive travelers.
• Eurolines: Long-established European international coach network (operated by Transdev) connecting cities and airports across Western Europe, comparable to Flibco in offering cross-border scheduled bus services.
• Megabus: UK-based low-cost intercity coach operator serving airport transfers and city-to-city routes in the UK and continental Europe—directly comparable to Flibco's value-positioning and to SLG's Coolbus intercity offerings.

Broad incumbents

• National Express Group: Major UK-based bus and coach operator that, until 2022, ran a parallel German long-distance coach business (National Express / ALSA) competing directly with FlixBus; operates a broadly diversified public transit and coach portfolio similar to SLG's multi-brand structure.
• Transdev: French-based multinational public mobility operator running bus, coach, tram, and rail services across Europe, the Americas, and Asia-Pacific; a broad competitor in the same tender-based public-transit and intercity coach segments SLG targets in Europe.
• Arriva: Deutsche Bahn-owned European bus and rail operator active across the UK, Ireland, and continental Europe; competes with Sales-Lentz in regional bus concessions and shares a multi-country, multi-mode operational model.
• Keolis: French public-transit operator (SNCF/Quebec Railway partnership) running bus, light rail, and metro systems in Europe, North America, and Australia; comparable to SLG as a multi-mode mobility provider delivering on tendered public contracts.
• ComfortDelGro: Singapore-listed global land transport conglomerate operating taxi, bus, and rail services across Asia, Australia, the UK, and Ireland; comparable as a multi-mode, multi-geography mobility holding, though with negligible presence in Luxembourg or Western Europe.

Regional players

• RegioJet: Privately held Czech bus and rail operator running yellow-coach intercity services across Central Europe with newer Western European expansion; comparable value-pricing coach model but operates in a different geographic core.
