Boeing Co. reported more cancellations for its 737 Max jet, which this week is scheduled to carry paying passengers for the first time since the planes were grounded 21 months ago after two deadly crashes.

Boeing said orders for 88 of the planes were canceled in November, pushing the total to 536 for the year.

The company reported 27 orders for the plane, although 25 were a new order by Virgin Australia that replaced an earlier, larger order for 48 Max jets that was scrubbed, accounting for a majority of the month’s cancellations. The November figures don’t include Irish carrier Ryanair’s announcement last week that it will order 75 more Max jets.
