Delta Air Lines (DL, Atlanta Hartsfield Jackson) has entered into a sale-and-leaseback transaction with Altavair concerning six A321-200s.

The value of the transaction, which is financed by investment firm KKR, was not disclosed.

"Due to our longstanding relationship with Delta, we were able to document and close on this transaction in very short order. As always, we very much appreciate the trust that Delta places in us to deliver on strategically important projects which are both time sensitive and economically important to their business needs," Altavair Chief Executive Steve Rimmer said.

According to the ch-aviation fleets advanced module, Delta Air Lines operates 100 A321-200s, of which it now owns 54. The remaining 46, including the six aircraft now sold to Altavair, are on operating leases.

Aircraft leased to Delta by Altavair also include three A330-300s and nine B737-900(ER)s, the ch-aviation fleets ownership module shows.
