National flag carrier British Airways is among the airlines to launch “Basic” transatlantic fares from April.

Along with BA, American Airlines, Iberia and Finnair are also offering the unbundled air fares.

Basic fares will not include checked baggage or a choice of seat, but passengers can pay to add those extras.

In-flight, the service is the same as economy, including meals and entertainment and blankets.

The airlines say the fares, which include carry-on luggage and one personal item, offer customers more choice.

In a press announcement, the airlines said those wanting to select a seat and have checked baggage would find a better deal in a bundle.

They will be known as Standard fares on BA and Finnair, Main on American, and Optima on Iberia.

Basic fares, known as Light fares on Finnair, will be the default fares on GDS systems, so agents must upsell for their passengers to be booked on a Standard fare on BA.

Travel dates and routes will be announced when the fares are launched in April.
