Air France-KLM is planning on selling a rare benchmark-sized seven-year bond next week in only the third issue this year from an airline company. The carrier follows Germany's Lufthansa and Australia's Qantas.

The deal, which is expected to be around €500m ($642m) in size, is to be sold by four banks after a four-day investor roadshow beginning at the start of next week. Launch and pricing is expected on September 11.
