Boeing has a delivery problem and it's not good for the airlines that rely on its planes

• American planemaker Boeing has paused some deliveries of its best-selling 737 MAX aircraft.
• The delays are due to a supplier's "non-standard manufacturing process" on the aft section of the fuselage.
• The pause comes just one month after Boeing resolved issues impacting deliveries of its 787 Dreamliner.

Boeing has halted some deliveries of one of its most important aircraft — again.

On Thursday, Bloomberg reported the American planemaker would have to pause deliveries of its best-selling Boeing 737 MAX jet due to production issues.
