From air to rail: Dutch airline KLM has announced plans to replace one of its daily flights between Brussels and Amsterdam with a high-speed train.

Train-led: KLM is partnering with high speed train company Thalys and NS Dutch Railways. From March 2020 one out of five of KLM's Amsterdam-Brussels services will be by rail.

Business and sustainability: KLM says the decision encourages travelers to consider their carbon footprint -- and frees up slots for long-haul flights at Amsterdam Schipol airport.

Quality match: The Dutch airline tells CNN Travel it's currently working on ensuring its train service matches the quality of in-air service. "If we can really build a product that is comparable to our current products, we will consider replacing more short haul flights in the future," says KLM spokesperson Manel Vrijenhoek.

Air-rail alliance: KLM isn't the only airline collaborating with the railways. Austrian airline runs AIRail, a partnership with ÖBB.

Daily connections: "Currently we are offering up to 32 daily train connections between Vienna and Linz, as well as three daily train connections between Vienna and Salzburg," Leonhard Steinmann, a spokesperson for Austrian Airlines tells CNN Travel.

Window watching: Train advocates don't only praise the lower carbon footprint afforded by rail: "The train journey is a chance to get some work done, relax and see some scenery," says train expert Mark Smith, AKA The Man in Seat 61.

On board experience: It's easier to get up and about on a train, and there's generally more food options for economy passengers.

Other alliances: German airline Lufthansa has a codeshare partnership with Deutsche Bahn (German Rail), pictured.

Eco-conscious: As travelers become more conscious of their carbon footprint, there's been a shift away from short-haul flights toward high-speed rail, where it's available.

Gear shift: Austrian also says it's hoping to shift short-haul flights to railways. "Wherever it makes sense, we are definitely interested in further shifting short-haul flights to rail," says Steinmann.

French connection: In France, AirFrance has what it calls a "commercial relationship" with SNCF. On TGV's Paris to Brussels route, a block of seats are administered as an Air France cabin.

Public reaction: KLM says the decision to make the move into the rail market was well-received by passengers and the general public.

Teamwork: KLM also says it hopes other airlines will adopt this strategy. "Together we can make a bigger impact sooner in reducing the footprint of the aviation sector," says Vrijenhoek.
