Alsa Grupo SLU
Spain-based ALSA is a scheduled coach operator whose IATA code 5I supports intermodal Bus&Fly bookings; it is not an airline and does not operate aircraft.
About Alsa Grupo SLU
Alsa Grupo SLU is a Spanish passenger-transport company whose origins date to 1923. Better known by the ALSA brand, it became part of the British transport group National Express in 2005; that parent company was renamed Mobico Group in 2023. Although ALSA has the IATA designator 5I, it is a coach operator rather than an airline. The code enables selected bus journeys to be distributed alongside flights in reservation systems.
ALSA has no aviation hub or independent flight network. Its relevant intermodal gateway is Madrid-Barajas Airport, where eligible Bus&Fly itineraries connect coach services with partner-airline flights. ALSA's much broader ground network serves cities, towns and airports across Spain, with additional international coach operations. Travellers should distinguish these scheduled road services from airline-operated sectors shown on a combined ticket.
Because ALSA does not operate aircraft, it has no Airbus or Boeing fleet and offers no airline cabin classes. Passengers travel aboard coaches, with vehicle layouts and amenities varying by route and service category. Depending on the journey, facilities may include reclining seats, Wi-Fi, entertainment or power connections, but these should be confirmed when booking rather than assumed. Any flight sector is operated under the partner airline's aircraft and cabin standards.
ALSA is not a member of Star Alliance, SkyTeam or Oneworld. It does not have an airline frequent-flyer programme, although the company operates its own customer loyalty scheme for eligible coach travel. On intermodal reservations, mileage earning, status benefits and lounge access depend on the rules of the airline marketing or operating the flight; the ALSA coach segment should not automatically be treated like an alliance flight.
The chief advantage of Bus&Fly is the convenience of placing eligible coach and air sectors in one planned itinerary, particularly for passengers starting beyond Madrid's immediate rail and airport catchment. The main limitation is that coach travel remains exposed to road traffic, and boarding, baggage handling and airport formalities differ from those of a connecting flight. Travellers should follow the itinerary instructions carefully and allow appropriate time at Madrid-Barajas.
Good to know
Flying with Alsa Grupo SLU — what to expect
Not An Airline
ALSA operates scheduled coaches, not aircraft. A 5I segment in a booking represents ground transport, usually as part of an intermodal itinerary.
Madrid Connections
Eligible Bus&Fly journeys connect through Madrid-Barajas Airport. Check the stated coach stop, terminal instructions and minimum connection arrangements before travelling.
Separate Baggage Rules
Coach baggage conditions can differ from the allowance on the connecting flight. Review both operators' rules, especially for oversized, fragile or special items.
Check-In Instructions
Do not assume the coach boards through an airline gate. Follow the ticket instructions for check-in, coach boarding and any required transfer at the airport.
Allow For Traffic
Road congestion can affect coach journey times. Keep contact details current and use the protected itinerary provided rather than arranging a tight, unrelated flight connection.

FAQ
Alsa Grupo SLU — frequently asked questions
Quick answers to the details travellers usually check first, from codes and locations to the practical basics that help with planning.
8 common questions
- Alsa Grupo SLU does not fly to any destination. It operates coach services, while flights included in Bus&Fly itineraries are operated by partner airlines.
- ALSA does not sell independently operated plane tickets. Prices for combined journeys vary with the coach service, partner airline, travel date and booking demand, so comparing flexible dates is sensible.
- It has no air destinations of its own. Its extensive ground network should not be counted as an airline route network.
- Alsa Grupo SLU has no air routes, so it has no longest flight. Its longest coach services are part of a changing ground network and should be checked against the current timetable.
- There are no ALSA-operated flight departures. Madrid-Barajas is the key airport for eligible intermodal coach connections, with the air sector departing under the partner airline.
- Originfacts compares live fares from hundreds of airlines and travel agencies via its partner Travelpayouts and never adds a fee. For 5I listings, travellers should confirm whether the result includes an ALSA coach segment within an intermodal itinerary.
- Alsa Grupo SLU has no airline hub because it does not operate flights. Madrid-Barajas Airport is the principal transfer point associated with its Bus&Fly intermodal services.
- ALSA does not publish an airline carry-on allowance because it is a coach operator. Travellers should check the coach baggage conditions and the connecting airline's cabin-bag rules separately.
