TUI Group is planning the capacity of its in-house airlines very conservatively, and will use agreements with other airlines to carry its tour operator customers if the demand exceeds its own capacity, chief executive Sebastian Ebel told Reuters.

The executive said that the airlines operating under the company's brand are conservative in capacity this year because of more competition on the market. He noted that the company prioritises higher margins and would not be expanding the number of in-house seats on offer to preserve them.

The travel group has agreements with multiple other airlines to carry passengers during the high season. The spokesperson confirmed to ch-aviation that the agreements are based purely on access to those operators' seat inventory and would not be through wet leases.

According to the ch-aviation fleets module, TUI Group has 34 jets on order from Boeing - twenty-seven B737-10s and seven B737-8s. The group's CEO recently complained about the delays in aircraft deliveries, saying that the company would be "significantly better off" if the jets arrived on time.
