LAS Líneas Aéreas Suramericanas

Anyone who looked at the cargo aprons in Bogotá in the 2000s and 2010s could hardly miss LAS: three-engine Boeing 727 freighters with Colombian HK- registrations, departing toward the Caribbean and the Andes. Today LAS Líneas Aéreas Suramericanas is history. This page puts the airline in context, shows the fleet development and helps you assign old sightings correctly.

LAS at a glance

LAS Líneas Aéreas Suramericanas was a Colombian cargo airline based in Bogotá with its hub at El Dorado Airport. The roots go back to 1972: that is when the company was created under the name AeroNorte. Cargo flights played the main role from the start, and in the mid-1980s the airline received its well-known name Líneas Aéreas Suramericanas – in everyday use usually just LAS or LAS Cargo.

The business model stayed the same over the decades: pure cargo, on scheduled and charter flights, mainly within Latin America and to the Caribbean. LAS did not carry passengers. In 2013 the airline joined IATA, and in 2014 it received a new logo and a reworked livery.

The end came in 2023. With debts of around 17 million US dollars, the airline entered a restructuring under the Colombian insolvency law, and the company was put up for sale. During 2023 LAS ceased flight operations. For spotters that means: there are no new sightings any more, and LAS lives on only in photo archives and logbooks.

Codes and callsign

• IATA code 4L: appeared in flight numbers and on cargo documents.
• ICAO code LAU: appeared in the flight plan filed with air traffic control and on flight trackers.
• Callsign SURAMERICANO: how the crews identified themselves on the radio.

The ICAO code LAU is the most important anchor for spotters when you evaluate old tracker screenshots or radio recordings. Why IATA and ICAO codes often have so little to do with each other is explained in the guide to IATA and ICAO codes.

The fleet history: from the C-46 to the 727

What makes LAS exciting is above all the fleet. Over five decades it reflects how air cargo developed in South America: first piston-engine veterans from the postwar era, then retired passenger jets converted into freighters.

Type	Number	Period	Spotter note
Curtiss C-46 Commando	6	1972–1993	Piston-engine freighter from the earliest days
Douglas C-54 Skymaster	3	1972–1988	Four-engine classic
Douglas DC-7	1	1972–1973	In service only briefly, destroyed during refueling
Douglas C-47 Skytrain	2	1976–1980	Military version of the DC-3
Douglas DC-6	4	1982–1999	Long in service, until shortly before the turn of the millennium
Canadair CL-44	1	1984–1988	Turboprop freighter, lost after an engine failure
Sud Aviation Caravelle	7	1983–2002	French jet with rear-mounted engines
Boeing 727-100F	5	1993–2020	Short 727 as a freighter
Boeing 727-200F	5	2002–2023	Stretched 727, the flagship of the late years
Douglas DC-9-15F	2	2002–2008	Small twinjet with a cargo door
Boeing 737-300SF	1	2019–2022	Converted freighter
Boeing 737-400SF	1	2021–2023	The airline’s last aircraft

The figures come from publicly available fleet overviews; numbers for historic small fleets may differ slightly in other sources. In 2016 LAS also ordered two converted Boeing 737-800s, which never joined the fleet.

The Caravelle years

Before the 727 arrived, the Sud Aviation Caravelle was LAS’s jet. Seven examples flew for the airline between 1983 and 2002. In 1987 LAS also started the connection to Panama with a Caravelle.

The 727 era

From 1993 the Boeing 727 took the lead role. First came five 727-100Fs, the short original version of the trijet, and from 2002 five stretched 727-200Fs. The 727 suited the conditions in Colombia well: it copes with shorter runways and high-elevation airports like Bogotá, and used examples were available cheaply as freighters. The 727-100Fs stayed until 2020, the 727-200Fs until 2023 – making LAS one of the late operators of this type in South America. The manufacturer of both versions is Boeing.

The step to the 737

From 2019 LAS added Boeing 737 converted freighters of the Classic generation to the fleet, first a 737-300SF, and from 2021 a 737-400SF. Compared with the 727, a twinjet burns far less fuel. A fleet renewal no longer succeeded, though: when operations ended in 2023, only the 737-400SF with the registration HK-5385 was left, and it too stayed on the ground.

How to recognize LAS aircraft

Because LAS no longer flies, recognizing it is mainly about old photos – your own or ones you find in archives. Three features help you:

You recognize the 727 itself by its typical silhouette: three engines at the rear of the fuselage, one of them at the base of the tail with the distinctive S-shaped inlet, with the T-tail above. You tell the -100 from the -200 by fuselage length – the -200 looks clearly more stretched. How to tell freighters from passenger versions in general is explained in the guide Recognizing cargo aircraft.

Routes and area of operation

LAS was a regional cargo airline in the best sense: the network spanned from Bogotá across the Andes, to Central America and the Caribbean. In May 2022, a good year before the end, the schedule included these destinations, among others:

• Caribbean: Oranjestad on Aruba and Willemstad on Curaçao
• Central America: Panama City
• Andean countries: Guayaquil and Quito in Ecuador, Lima in Peru
• Venezuela: Caracas

On top of that came charter flights. In earlier decades the network was broader and also reached Miami, Mexico and numerous airports within Colombia. The partners for which LAS carried cargo included large network airlines and express services.

In the Colombian cargo market, LAS stood alongside much larger names. Avianca Cargo flies Airbus A330 freighters on long-haul routes, Aerosucre also relied on older Boeing freighters for a long time. Anyone spotting in Bogotá could thus see generations of cargo aviation side by side.

Accidents and incidents

Like many cargo airlines with old aircraft, LAS experienced a series of serious accidents. Publicly documented ones include:

• December 1991: A C-46 hit a hill on approach to Bogotá. All eight people on board died.
• January 2001: A Caravelle crashed during an attempted emergency landing near El Alcaraván Airport. Three of the six occupants died.
• December 2003: A DC-9-15F crashed near Mitú in southeastern Colombia, and the three-person crew died.
• May 2018: The 727-200F HK-4637 landed hard in Bogotá and the nose gear collapsed. Nobody was injured, and the aircraft was repaired.
• October 2020: The same HK-4637 ran off the runway while landing in Valencia, Venezuela. Again there were no injuries.

In the early years a DC-7 and a CL-44 were also lost. The list shows the conditions under which cargo flying with older equipment often took place in the region: high-elevation airports, difficult terrain and changeable weather.

LAS as an archive sighting

For your logbook, LAS is a closed file today – and that is exactly what makes it interesting. Every shot of an LAS 727 documents a chapter of aviation history that will not return. How valuable such a sighting is by comparison can be judged with the guide to the rarity of sightings.

If you digitize archive photos, a quick cross-check is worthwhile: registration, type and date should fit together. A 727-100F in LAS livery after 2020 would be implausible, for example, because the -100 had been retired by then. Plausibility checks like these make your archive more reliable.

Common mix-ups

• Confusing LAS with LATAM – the names sound similar, but LATAM Cargo is the cargo division of the Chile-based LATAM group and flies widebody freighters.
• Taking every HK- 727 for LAS – other Colombian cargo airlines also used the trijet. The titles or registration must match.
• Assigning a 767F to LAS – a 767 is not documented at LAS.
• Mixing up 4L with the ICAO code – 4L is the IATA code, LAU the ICAO code.
• Equating the 727-100F and 727-200F – the -200 is much longer, and both versions flew in parallel at LAS.
• Taking LAS for active – flight operations ended in 2023.

Conclusion

For over five decades LAS Líneas Aéreas Suramericanas was a piece of Colombian cargo history – from the C-46 through the Caravelle to the Boeing 727. With the end in 2023, one of the 727 freighter fleets that shaped South America until the last disappeared. Anyone with an LAS aircraft in their archive now owns a genuine historic sighting; noted cleanly with registration, type and date, it stays unambiguous.
