When Turkish Airlines announced last month that it had just placed its largest airplane order ever with Airbus, Boeing (BA 2.06%) investors couldn't have been pleased. So perhaps today's news will suit them better: On Tuesday, Turkish Airlines announced it will also be buying planes from Boeing.

According to Boeing, TA announced today that it has committed to order:

  • 40 Boeing 737 MAX 8 airliners.
  • 10 larger 737 MAX 9s.
  • 20 next-generation 737-800s.

Adding to the good news, TA took out options to purchase 25 737 MAX 8s at a later date.

None of these orders are yet set in stone, but Boeing is working toward completing the deal, which it says is worth "$6.9 billion at list prices," or even $9.4 billion including the optioned MAX 8s.

The order isn't quite as big as the one Airbus won last month, but it's a whole lot better than nothing, and it helped to lift Boeing shares 0.5% in Tuesday trading. Boeing closed at $87.21.
