New long-haul low-cost carrier Level says its bookings have “taken off” after more than 100,000 tickets were sold since its launch.

The airline – part of International Airlines Group, which is also the parent company of British Airways – launched on March 17.

Since then, the brand has had over 700,000 hits on its website as customers search for flights from Barcelona to Los Angeles, San Francisco (Oakland), Buenos Aires and Punta Cana.

More than 60 per cent of customers have come from mobile devices.

IAG chief executive, Willie Walsh, said: “Selling more than 100,000 tickets in such a short period with a new brand is incredible. The response has been fantastic in all markets. We´re enabling many people to fly longhaul for the first time and stimulating demand by providing them with more choice.

“Level is breaking the mould. We will continue to offer amazing fares. Customers can chose add-ons for their flight from a menu of options.

“This is just the start. In summer 2018 we will have more aircraft and will operate more destinations from Barcelona. We’re also planning to expand Level operations to other European cities.”

The first flight will take off on June 1, and travel from Barcelona to Los Angeles. Barcelona to San Francisco (Oakland) starts on June 2, to Punta Cana on June 10 and Buenos Aires on June 17.
