Bloomberg reported that Southwest Airlines will push back $1.9 billion of spending on aircraft during the next 10 years by delaying the delivery of 67 Boeing 737 Max 8 aircraft by as many as six years.

Bloomberg also said that Southwest will push up delivery of six 737-800 orders to 2017 from 2018.

Bloomberg also noted that Southwest still plans on taking delivery of its first Max 8, the newest version of the 737, in 2017.
